I. TINY NOTES
1) I would recommend to set as default in Ja2_Options.INI :
Graphics Settings -> SMALL_SIZE_PB -> TRUE
It seems these maps were designed with this setting on.
North boundary still remains not enough for comfort. But at least you can see the outermost tiles (shoes of chars)
2) I stumbled accidentally upon solving the backpacks problem when dug deep into APBPConstants.ini. It helps a bit since one factor gets removed. Still the problem of displaying wrong estimate APs spended for paths holds. Too much influencing factors like skills, perks plus terrain impact and so on. I think that's a common case and not specific for this mod.
The fix is return deleted entry "AP_MODIFIER_PACK" from original (vanilla) into APBPConstants.ini and set it to 0.
3) Some portraits don't have camofaces!

4) Such thing can happen when you move items through assignment "Move Item". As you can see all items are somewhere OUTSIDE THE MAP! And of course you cannot take them by no means whatever... But one more often problem is spawning items in such "places" while the most tending Item being "scopex10". Sectors with spoiled spawning I remember: H9, F13 (one level down).

Is there a way to force delete (in game, when it already happened) such "grey out" items cause they are really buggers. If you Ctrl+Click a "scopex10" from a merk inventory it flies out from the map and stacks with this "grey out" e.g.!
5) Frazzler. Does this nick sound ok to you? Sounds like meaning a brute who tortures people to a frazzle, a bit confusing. Because if I understood right it should mean a man beaten by hardships and ordeals, like FrazzlED. Good sounding to me is something like Frazzles. May be it's just my poor perception of the foreign language...
II. STRATEGIC MOVEMENTS
1) There's another terrible inconvenience I found. Prohibition to turn off the check mark "Go to Sector" while using boundary move interface in a hostile sector or NOT to move the last merks out (which is the only way of moving out/retreat in a hostile sector). As result 5 min of in-game time disappear along with all strategic events including may be crucial ones! It can be very good seen when moving takes place during transition from one hour to another when merks' assignments (being strategic events) don't work.

2) I realized that return after retreat or reinforce with delay were completely removed from the game! Squads wanting to join a battle never reach the destination till the battle is over as their arrival is being delayed for 5 min for everlasting. Yes, one time 5 min delay for the retreating is good idea but all-round prohibition to join a battle for squads seems quite bad!
3) I think moving between underground sectors should take the same 5m-XXh XXm like above or have their own timing but not less than 5m minimum. It would make strategic movements more consistent overall.
4) Turns take no time at all. You can play through thousands of turns while in-game time isn't progressing a sec. Is it changeable?
5) Can I set up things described above by some txt editing like ini/xml or it's all hard-coded?
III. HEADS
First I said it's not important but now I changed my mind coz it not only Mendax and thus the whole Carmen quest goes broken. That is what happened with Morris:

And then again when I got the head by transformation cheat:

Please check the quest file and say what ID's Carmen will need for heads. He needs 4 of them to join me, right? So I can make them by transformation cheat!

IV. GRENADES
1) Fragmentation grenades do not have fragments set up. Is it for balancing purposes?

2) Could you check Molotov and Flarebomb on being set up correctly to give a light? May be I broke my install by editing xml's. But I have feelings they were not set up correctly initially.
3) I failed to understand how to set up light for fire. And flares themselves. I wanted to increase radius and duration for flares like I did for gas&fire grens. If I remove tag "flare" and set animation to "flare" it don't give a light at all! Where to edit default "tagged" flare I did not get. Did fire need a buddyitem to light up space around, right? Would someone be kind to give some hints about it all?
