Unearth hangs after opening several maps

[Loobinex]

I was looking for a good map to screenshot, and from the browse map menu was double clicking maps to load (including the textures). I started at sapphire realm map 1, and went down the list. Each map opened slower than the last, until at map 7 unearth hung and windows offered to close it.

Restarting unearth and doing the same, it had severe slowdowns again, but did not completely freeze.

Ran a test where I opened 1000 random maps on a loop without crashes and it stayed in the 300ms range. Though I did that while in the Godot editor. I think I do sometimes get crashes with the compiled version.

RNC decompression slows things down a lot (occurs once) and it might be a cause of crashes. Perhaps when opening another map while decompressing another map.

Or it could generally just be opening maps too fast one after another causes an issue. I should probably add a check to determine whether the map is fully opened before allowing another map to be opened.

Saphire realm maps are not rnc compressed.

Edit: Checking some more, it seems specifically map00006 and 7 from that campaign that take several seconds to open.
