**How/when does this happen**: From the error, I judge that the plugin is having problems with [QuickShop](https://www.spigotmc.org/resources/quickshop-reremake-1-15-ready-bees-bees-bee.62575/)
**Other information**: The error seems to be on your side. If not, I'll report it to the QuickShop's author. The issue occurs every time player tried to move, and it seems to cause FastBreak/Place false positives. I guess there is some issue with interactions, where QuickShop checks for sign interactions for shop signs, and Matrix checks that too, resulting in mismatch between plugins.
