On overlap tile bug?

I have been working on this game for a few weeks with my students and we have a persistent “bug” with the ‘on sprite of kind player overlaps tile’ block.

The selected tile keeps reverting to the “blank” tile and when we try to reset it all of the in-game tiles are missing. Our current “fix” is simply opening the tilemap, clicking Done, selecting a different tile in the overlap block, and finally reverting to the original tile.

Has anyone else run into this issue before or know how it can be fixed? I feel like it is a caching issue of some sorts, but all my students are experiencing the issue (we did all start with the same base of code), so it would have to be some unseen caching issue, perhaps burried within the Javascript explorer or code?

Any help would be appreciated!

I believe this is https://github.com/microsoft/pxt-arcade/issues/2281, which was fixed in https://github.com/microsoft/pxt/pull/7386. The fix is in beta and it looks like it’s working to me, and that fix will go out with the next release after a few other things are fixed. Sorry about that!

Glad to know it’s already been addressed. Thanks for the quick reply!
