I noticed you guys had my mod in the conflicts list, can you explain in what conditions do those freezes and crashes occur ?

Played a bit with it and no crashes so far while running a complex script in the PB set to loop.

EDIT:
Ah, it seems you also attach a script on the programmable block and because only one script can be attached to an object type, one of them is ignored.

You can fix that by not depending on the script attachment tag, since you most likely already monitor cubegrids and stuff.

The thing is, any simple script mod can cause you issues by blocking your scripts or you blocking theirs (depending on the order), this issue needs to be addressed game-side though, I'll post an issue on the git page.
