I also included Snow! Real Magic screenshot - just in case - because I saw that mod creating some incompatibilities in the past. That boat screenshot was added to prove that ice was actually expanding in sizes during winter. The area these pictures were taken is traverse_autumnalwoods. Season was summer.

Please, don't be fooled by some blocks absence - in those areas ice was never generated in the first place, or it was manually destroyed / melted via torch by me

Did you update the config files as mentioned in #133?
