When running Endless Gateway of Apothic Invaders at some point after 50 waves, it simply implodes and gets struck by lightning. I have 2 videos, each for 1 gateway. One of them implodes at wave 66 and the other at wave 84. I've sped them up. The server console doesn't show anything.

Apotheosis 8.4.0

To kill the mobs I am using Mob Slaughter Factory from Industrial Foregoing. And if it helps, the platform is 41x41.

Tried with a few more gates. It failed on: 91, 30, 103.
Also, apparently, if you kill the wave too fast, during later waves, the rewards don't spawn quick enough before the next wave, so you do not receive them. I passed wave 100 and didn't receive Sigil of Supremacy.
