Game crashes right after toon appears in world. This started after I finished a 3x3x4 farm made from mossy brick blocks.

I had removed forestry to keep playing. Now I updated to buildcraft 7.99.24.2, added forestry zip back into mods and regenerated my world.
The moment I add the last farm block to the 3x3x4 structure the server crashes and it continues to crash every time I try to reload it.
Just to note, there are no buildcraft pipes on my server, and there isn't anything trying to interact with the farm structure I built either.

I used to the beta 5.8.2.394 instead of the release and MC stopped crashing.

Please try with the latest version of buildcraft (7.99.24.2)

The last release build of forestry was quite a long time ago but unfortunately curseforge puts it right at the top of the page. The latest beta will have more bug fixes in.
