There's this problem I'm having when my project/game is online. A lot of weird things are happening when the opacity variable is used, but I can't troubleshoot it because it doesn't happen when I run my own test world.
I tried to come up with an explanation of the error, but it's too inconsistent. Below I'll post some screenshots, and some explanations to those specific cases. Maybe someone can enlighten me.

-You'll notice in this screenshot that for some reason you can see the tile past the opaque tile. I don't know how to describe the view after that...

-In this one, I put a red box on the opaque tiles that surround the room. You'll notice that you can see part of the building placed next to it on the map, which is not intended.
This problem was random, and I have no idea what to do with it. Maybe it's something with the host files..? I don't know, I really can't figure it out.
