[2019] Color Bug

Whenever i use the Multi Select tool, some tiles change their color almost like they were selected, which they arent. After that its enough to just hover over any tile with my mouse and they will change their color to this.

i can fix it by selecting every tiles that has this bug with multi-select and then switch to my axe.

But then it will repeat and every tile i hover over with my mouse will get this bug.
