I have several placable-off-grid entities placed by script, and if I set tiles under them they're deleted. Right now I'm going to just move those entities away and put them back after calling set_tiles, but it'd be nice to have a flag to disable this behavior

Entities are cleared only if they collide with the tile: putting water under a building for instance will delete the building.

If you don't want your entities to be deleted don't make them collide with the tile type you're putting under them.

They have to collide because they're placed by a script in a location where players shouldn't be able to place buildings.

You could move them away, set the tile, then move them back.

That is exactly what I did

Thanks anyway <3
