Im working on SSBYOND 2, and all of a sudden my map icons are blank and unseen. I tried re-compiling and updating the map, but nothing happens. I checked all my icons, and all icon states had the appropriate names. The icons only reappear in the map editor after i close and oopen the project about 6-7, and then different ones dissapear. The icons can be
seen in both online and offline tests, however.
Could me running out of memory
This bug requires some kind of demo or project file for us to test. Otherwise it can't be verified.

Of related interest would be knowing how much memory your system has, and if this occurs on other computers.
