Lo-Fi Games

Recently been having a few problems with mines. When building in various places they tend to make a portion of the map inaccessable. I built one next to traders-edge and now half the map is blocked by invisible walls. I know if i deleted it it would stop but i cant get to it Because of those walls. ...

A few crashes I found were as follows:

1. upgrading a training dummy when someone was using it.

2. switching backpacks when there is no room in my main inventory for the backpack being replaced.
Thats about it so far
