I've tested this functionality in the Wilderness Black Chinchompa area, when the chinchompa is caught, and shows as "Reset Shaking Box" the plugin doesn't "see" this.
However, testing within the same login session and java PID, I teleported to Feldip Hills to test Red Chinchompas. The plugin does "see" when a chinchompa is caught and resets the box appropriately.
In both scenarios the plugin otherwise functions as expected. It will lay down the trap or reset the box trap if a chinchompa fails to trap.
Happy to test anything further, but this is my initial review.
Details:
Platform: Windows 10
Java: JDK-23.0.1.0
MB version: 2.0.56/8 - tested both recent versions
