I managed to get SLX and ACE to work together fine, there are of course some problems, but none that weren't already present in SLX (understandable due to the nature and ambition of the project). I had my command line configured as such, running beta build 61062:
"E:\Program Files\Bohemia Interactive\ArmA 2\beta\arma2.exe" -nosplash -mod=@ACE -mod=@ACEX -mod=@CBA [many different mods, effects mainly] -mod=@SLX [more mods, islands, units mainly] -mod=beta -world=empty
No problems with wounding what so ever, works just like it did in SLX + Vanilla.
This seemed to work, at least for me. Currently trying to cut down SLX to see if I can get maximum compatibility, I've also implemented the new zeus AI without significant problems.
