Doing nothing at 3 priorities

I noticed some unusual conflicting priority numbers. As seen below, I have priorities 2, 4, and 7 for doing nothing. Refreshes after quitting/starting game, so no save file.

Seen using OC-255502.

Also, steps/screnshot 2 may illustrate another graphical issue. The 2's just don't look like they are in the right position.

1) Mark an area for digging, priority 1

2) Build a cot, priority 2

3) Cancel the cot build

4) Mark the area for digging, priority 3. Notice the 2 underneath the 3.

5) Build a cot, priority 4.

6) Cancel the cot build

7) Mark the area for digging, priority . Notice the 2 and 4 underneath the 5.

8) Build a cot, priority 7 (I didn't use priority 6 as it would mask the other numbers)

9) Cancel the build. Voila, 3 overlapping ghost priorities.

10) Nothing going on here. Just a player ignoring the bugs and loving this game!
