Even with my hourly and daily savegames, the attacking patrol seems broken with non existant soldiers.

The interesting thing is that seven of them climbed the roof of the Hicks !??
Vince was the first on the roof and the enemies followed him and often had an interrupt when they reached it.
I didn't know they could climb roofs with stracciatella.

And when I reload after the battle at the Hicks, a message box appears while the game is loading and says I have the bug responsible for mercs disappearing. It says to send my savegame to Dave and Kris.

I played the fight at the high school again and again and had several messages with the BETA and TEST flags enabled:

A message box: "Enemy administrator killed with ubGroupId of 3, but the group doesn't contain elites.

A text on the tactical screen: "AI 24 got error code -3 from handleitem, doing action 27... aborting deadlock!"

The log (after a crash): "{...} Assertion failure [line 1090 in Build/strategic/Queen_command.cc]: AddPossiblePendingEnemiesToBattle(): Logic Error -- by Kris"
