Acid vent looks not work , too (debug)

[ZhilkinSerg]

Probable cause #32491, but could be broken earlier.

[ZhilkinSerg]

Do you have a savegame to test? Debug spawned gas vents are working and spawn fields (maybe not in same amounts as previously, but still).

[Swootch]

The savegame is too large, over 500 mb.

[ZhilkinSerg]

Zipped?

[Swootch]

Zipped it's 77 mb, still way over the limit.
I've made a new character in a new world and debugged myself to the next mine, and saved right in front of a broken gas vent, hopefully this is helpful.
