Oh i recently got the same error on same versions, but could not reproduce it when trying clean setup: https://github.com/Keurig-Creator/XPBooster/issues/2 I think i was updating from 1.3 but not sure 🤔 Anyway it was fixed by just wiping configuration folder and redo. Now i'm on 1.3.2 and it works fine…

I will go ahead and fix this issue if either one of you could reproduce it.

I really do not know what is the cause, because it keeps happening, I will put the original files, maybe some translation is not compatible or I do not know. This is an image from today

By chance are you using permission based multipliers? So basically it would be xpbooster.multiplier.5 for example. Could you send your settings.yml

I haven't edited the configuration much, most of the work I did was translating and removing boosters from the days https://pastebin.com/id7ffj9f

[Keurig-Creator]

I’ll fix it later tonight after work

@Antoniova1 Fixed this error in the update :)
