i started a new game with omni, angels, bobs + others and no vents have spawned(https://mods.factorio.com/mod/geothermalgen), disable RSO and they spawn > https://puu.sh/FnQKu/f04a569c3a.png

I'll try to take a look and a config for this mod.

any update?

New version with support for vents is up now.

since i updated with support for this the vents spawn but i can't place the geothermal gen on the vent

Thats strange - I'm not sure how RSO could have caused that. Is it possible that building is so large that it doesn't work if vents are close to each other?

it doesn't work on a single vent by itself and it works when i disable rso

I did some debugging and.. I can't do nothing about it at this moment.
I'll go to forums and check if it's a bug with base game or I need to do something I'm not aware of in RSO.

ok thanks

Due to game devs stating that issue with misaligned resource is not a bug I've removed support for geothermal generator mod. RSO will now let base game spawn resources for this mod using normal map gen (it can spawn those properly - mod's can't due to lack of support on game side).

after the newest update the vents are still there but i still can't place the generator on them, any ideas?

Any of them that were placed by RSO already are invalid. Only new ones will work.
