[0.18.17] Crash in map editor on 'remove all entities' clicked: "Character to remove not found."

[cubicgraphics]

I was using the map editor on an empty world with mods to play around. I placed a few remnants and other objects down. Then i clicked on the 'remove all entities' button and the game crashed.
i loaded the game again with the mods and clicked it again and it crashed again.
It was version 0.17.79 with bobs mods, angles mods and pyanadons mods.
I thought it was the mods crashing the game but to check i updated the game(which disabled the mods) to the newest version and opened the map editor again on the same game save. All the modded content was gone but when i clicked on remove all entities the game still crashed. I tried this a second time too and it still crashed.

The log when i had mods and it crashed, and a log when i didn't have any mods are attached

Thanks for the report. It's now fixed for the next release.
