TD 31550, Windows 11.
Specific function called Nudge wasn’t found in my extension. Other functions worked. I renamed the function to TESTER. Works fine. Rename it back to Nudge, works fine.
It wasn’t tied to saving the ext. file because I did that before and it didn’t fix the issue. Not sure how to troubleshoot this better; obviously it’s hard to replicate because usually when creating a function, it’s callable right away!
