Extension Tools menu breaks after reload.

[WildArticunoAppeared]

Sometimes the Extension tools menu breaks and looks like this:

It doesn't show all the tools and I can't even use what's there, as the entire menu disappears when I hover my mouse over it. Which really sucks because one of those tools is the Resettle NPCs, which is a really nice thing to have, so I'd really like to be able to actually use it.

Well, I'll need client.log so I can see the error and a list of the mods you have that add extensions, since I don't make those.

Here's a client.log from a session where this bug does not occur.

Further testing indicates that this bug occurs after a tModLoader reload. This is a log after I reproduced the bug:

The mod that adds the extensions I have is "Cheat Extensions for Hero's/Cheat Sheet" (CheatExtensions). Disabling the mod actually fixes the bug, as one extension (Mob spawn rate) remains and is functional.
