game completely broken, lua cache cleared,balanced annihilation doesn't even start with ais, tech annihilation starts but in first second all ais get clobbered.
same install from 87.0 lobby version was 143 then i think, now current doesn't work - was updated with the springlobby updater, since then ai games no longer work.

translated stack-trace:

as usual, no really usefull info in the AI part.

have you tried other AIs? KAIK, RAI. E323AI?

if possible, give a script.txt (battle configuration) file that crashes for you.
