Hi @latunda :slight_smile:

The team is asking for logs, verse files and/or the private island code so they can do some detective work.

To reproduce, you need a PUBLISHED map which already has the error: code on the left and then try to submit a new build which contains the fix on the right

Our code did not cause any errors during publishing but started causing issues after the update ( [STABILITY] New update introduced new errors in published map as the result it stopped loading )

“code”: “3612”,
“severity”: 8,
“message”: “Qualifier on definition is invalid; the class boss_battle doesn’t define Bosses.”

When publishing a new build with the fix we noticed that the portal checks the currently published version and reports the error that does not exist in the new build, preventing you from addressing the issue.

You can no longer reproduce with our map since we found a workaround, but there were reports of the same issue (validation uses the published build instead of just validating the build which is being submitted) from other creators in this forum.

hi @latunda

There was a similar publishing problem in this thread and its not fixed by clearing the remote source like in 40.00 used to do.
