After 1.1.71 Py mods are not working

[Criperum]

After the game updated to 1.1.71 all Py mods are red in mods list. No Py resources, Py buildings etc. Is it possible to fix that or i have to downgrade the game?

[DaleStan]

Yes, you can downgrade.

What errors are showing on the disabled mods?

[Criperum]

No errors. I'll try to add mods one by one to find which of them causes the trouble.

It was something call Py Energy and Pollution (or something like that). I removed it and cannot find it anymore on mod server. Probably it was removed but somehow stuck into my mods collection.

It's not so much Factorio that is an issue here, but pY having had a HUGE «2.0» update, and the unofficial pY pollution and energy mod hasn't been updated.

It still is around on the mod server, just deprecated : https://mods.factorio.com/mod/pypollution

I suggest that for games started with «pY 1.0», you stick with other (pY and non-pY) mod versions released before «pY 2.0»
(because the gameplay has changed quite a lot anyway, and your base is likely to be a mess)
I also did so for Factorio itself (that game folder frozen at 1.1.70), just to be sure...
