In the Area 4-2 miniboss fight, the bottom-left door sprite disappears when the miniboss tumbling around is on the same line.

Drill Dozer (USA)-0

Tested with mGBA 0.9.3 using default settings on Windows 10 64-bit and Switch. The issue is not present in old builds. It seemed to break specifically with 6199-d61d9ef.

Bug report ZIP (added a save state that works in 6198-ff0b7af)

0.9.3 and 6199-d61d9ef:

Bugged.--.0.9.3.and.6199-d61d9ef.mp4

6198-ff0b7af (correct behavior afaik):

Correct.--.6198-ff0b7af.mp4

    d61d9ef doesn't affect emulation at all, so that's kinda strange.

    Ah whoops, 6199 is labelled with & links to d61d9ef on the builds page, but the actual commit in the title bar is 031049c.
