[0.15.26] Save corrupted when uninstalling mod

[evildogbot100]

I make a test mod with a modded straight-rail entity that have no collision_mask. To reproduce the bug, simply load the mod, place 2-3 length vanilla rail, place modded rails completely covering the vanilla rail, then save. After that, remove mod and load the save. The save is now unloadable without the mod.

So it seems that our check to not allow any rails on the same location is failing in this case, it needs to be fixed.

Is it related to this viewtopic.php?f=23&t=49820

Hello, i fixed this bug in a way you might not like. I just disallowed specifying different rail categories.
It never worked, it was rather a "plan to make it work someday" than a functionality. We have too many other things on our hands than making this, sorry.

Do I just accidentally killed my own mod? Btw, this bug doesn't happen only for different rail category, normal rail category also bugged.

Well, it wouldn't work anyway, so you saved some time.

Nah, it's submitted already. I'm not saving any time, sadly.

Sorry for that. One day, we might make make different rail types possible.
