Bots not reacting to players after first death with HC

Hello,

we are using the "nightly build" from 20210412-2100UTC+2 from github (aka download of any files, then exporting as pbo).
We are occurring a weird behavior where the AI is ignoring any player past the point of the first kill They are running around, but not doing anything. As long as a HC is involved the AI is ignoring the player in any scenario after the first kill. We have tried certain scenarios:

One HC + ACEX + LAMBS (all 4 modules) -> Not reacting
One HC + LAMBS (all 4 modules) -> Not reacting
One HC -> Not reacting
No HC -> Reacting even after respawn

Could you look into this, please? Also would a ACEX integration parameter be possible? Maybe even more HC for better AI play in higher waves/with more AI?

Thanks a lot :)
