- In GZDoom, the crushers kill the boss brain (thing 3734) and a custom DEHACKED monster (thing 3725) residing within sector 5007. However, two similar setups with custom monsters (thing 176 within sector 1477 and thing 143 within sector 5005) are not affected, even though the crushers activate there too. It seems that the exploding barrels in these sectors do not explode for some weird reason.
- In PrBoom-Plus, the reverse happens: both thing 176 and thing 143 are killed, but neither the boss brain nor the custom monster (thing 3725) within sector 5007 are affected due to the barrels not exploding.
Save files from both GZDoom and PrBoom-Plus are attached. Please do note that in GZDoom the switch increases the kill counter by an extra 4 points (totaling 5) because the switch also crushes 4 lost souls, which are not counted towards the total kills percentage in PrBoom-Plus.
Unfortunately, I haven't been able to isolate the issue in a simple test map. In all my attempts, everything seemed to work fine - even when I took the original map and removed everything from it except the affected areas.
Tested in GZDoom 4.3.3 and g4.4pre-39-g2bde2d826.
