Crash when moving Basic Filters while editing

[Volpamonhub]

Is there an existing issue for this?

• I did not find any existing issues.

Current Behavior

I was editing 9 Basic Filters (the editing window was open), and I moved the Basic Filters from my hotbar to my inventory while the filter editing window was still open. The server immediately crashed. After the server rebooted, the filters had disappeared from my inventory.

Expected Behavior

What I expected to happen was either the hotbar to be locked, preventing item movement, or the editing window to automatically close when moving the filters.

How to Test

1. Open the filter editing window for several Basic Filters (I had 9 filters).
2. While the filter editing window is still open, move the Basic Filters from your hotbar to your inventory.
3. Observe that the server crashes immediately after moving the filters.
