I'm making a test map just learning how to use the editor and I've created a memory leak somehow. RAM usage just raises while doing nothing. It doesn't happen in other modules so I don't think it is the editor its self?
Is there anything I can do to find what has caused it?
I'd always go for scripts first, even small mistakes can lead to spectacular effects sometimes. Otherwise, try disabling other parts of the mod, added around the time of the ship placement, and see if anything changes. Hard to say what it could be.
