Not sure if this is intended but pretty sure this is a bug.
The Red Bush does not work in Infinite mode, I've tried making a new save and getting to the Cabin before the time doesn't activate. I've had longer saves that it didn't work on, sometimes doesn't work in Story Mode either. Again I make sure to get to Cabin before 3am and it doesn't activate when the time comes around.
I have tested back on 0.8.1 and 0.8.2 and it's affected both Infinite and Story mode. I was playing a Story save made on a not stable 0.8.2b patch back on test version 7 that didn't work. Making a new Story Save did seem fix my problem for the Red bush, but did not fix the problem for a new Infinite save. The grass is also still bugged in the Red Bush dimension being extended pixels in form of triangles of each grass PNG.
I'll try update the post as I get further in a new save on current stable patch/update of 0.8.2b and see if Story save gains the problem with Red Bush over time, and report any new information.
