Using the delete tags tool, the game crash if I selected some tag not created by this mod!
I tested in the tags created by the mod YARM (https://mods.factorio.com/mod/YARM)
883.530 Error MainLoop.cpp:1284: Exception at tick 107427447: The mod Map Tag Generator (1.2.1) caused a non-recoverable error.
Please report this error to the mod author.
