To reproduce you just have to teleport to any location and the spell charges should be stripped away. I've yet to test if it's certain locations, but I believe it does not matter since it's a random occurence when portalling and it does not happen "all the time" yet (hopefully not).
When you reach a destination, it'll show a casting emote on your toon then a spam of "No uses or preparations left for that spell" will show up in the console tab.

It has also been pointed out that when someone experiences this bug, others will see a weird effect like a fire breath/cone of cold spewing out of the bug victim when they load into the destination.
I have also noticed that the spells it strips away is random, sometimes it's just a few lower circle ones, most times it also strips away even ninth level spells. Hopefully this problem can be fixed soon, for it's just a really bad hassle to deal with. Thank you for reading this post.
