Attached is a small test quest created in 2.10 which has the rules "No Rope 2 Flashing" and "No Bubble Flashing" set. These rules do not import correctly in Build 2183.

(Link will only work for 10 downloads so devs should make a copy)
"Ghini 2 Flickering" and "Ghini 2 Transparency" also don't import.
Test file 2:

(also limit 10 downloads)
I have also noticed that the custom quest "Labyrinth of Dinus" has the wrong Lanmola 1 tiles, but I have not been able to replicate it (in the "Temple of the Sand" level)
I also have not been able to replicate the solid dive warp tile that is occurring in the "Garden of Evil" level.
