Hi noname1848,
Thank you for reporting this issue and providing clear steps to reproduce it.
We take bug reports seriously, especially those that could affect game stability.
We’ll investigate the interaction between the CT Quest System and RPG Maker MZ’s Erase Event command using the steps you’ve provided.
If we can reproduce the issue, we’ll work on a fix and release an update as soon as possible.
We appreciate you bringing this to our attention and helping us improve the plugin.
