Summer and spring work fine;fall is the only one thats messed up i think
It worked fine for me till I activated the spring.
It's not messed up, it's just very... post-modern. It's a metaphor on how the leaves can make anything look like its been through coding hell and back.
It's due to it changing the tileset in your house. I'll see about it only affecting the outside of the house, unless there is actually changes that are made to the inside besides possibly the leaves/snow/etc particles.
