[Lou][2.0.44] ghost tiles appearing once, but not where they're allowed

[Quezler]

After loading the world you can place 2 ghost tiles here, after removing them you can no longer place them.

It seems vaguely related to the player/controller position, if you move around a bit you get ~2 other random tiles the placement succeeds once on.

The overgrowth soils have an empty collision mask and only allowed tiles either so its not like i am doing something completely unheard of.

Reproduction steps: download and unzip the mod, load that save, ignore the parameters migration, grab either uranium and try to place it nearby.

Thanks for the report, fixed for 2.0.46.

The primary issue was, when refined concrete was a effective cover for snow, the game tried to autofill it and then saw that satisfies the place-as-tile conditions of an item, which then replaced the autofilled tile.

What made it produce only a few tileghosts is, that after the radioactive concrete tileghost has been placed, it became the new effective cover for snow tile, which however violates its item's place-as-tile conditions and thus is not autofilled. (sometimes 2 tileghosts are produced because of different snow-tiles bellow them).
