AE2 generates a toast(?) when a crafting job finishes. More information below.

Describe the bug
My game crashed 3 times and this perfectly synchronises with the completion of a crafting job, i cant see the pop up and had no terminal open at the time. Cant confirm ae2 is the cause though, cant reproduce.

Cant reproduce relibably, afaik it happend only when i had the terminal open and when crafting items from mekanism, take the last one with a grain of salt.

This is potentially on my end but it appears there is another factor at play - Advancement Plaques is screwing with TC internals https://github.com/AHilyard/AdvancementPlaques/blob/1.19/src/main/java/com/anthonyhilyard/advancementplaques/AdvancementPlaquesToastGui.java

I can implement something that may prevent this particular crash but I have no idea what other issues may arise from this.

Advancement Plaques should really be using their own GUI Component and utilizing the ToastAddEvent to capture advancement toasts instead of hijacking the toast component.

Can't really add to that, i could also report it to advancement plaques and see what they know.

I'm having the same crash when joining my server. I don't have advancement plaques installed.

Closing as I don't think this is resolvable by me.
