The error is now fixed but the issue of balloon icon not showing on top of the NPC is persists for me. I used a new RPGM project just to be safe. don't know if it matters but I'm using v1.9.0 version of RPG Maker MZ.
Sorry, try again. 1.2.6 I updated incorrectly.
Everything seems to be working fine now. Thanks for all the hard work. :)
Thanks for the report and testing, I'm glad I found the bug.
