Guild Wars 2

Pretty sure this is a graphics option, specifically the one about character models at the very bottom of the settings list. Try moving it from lowest to low.

Schlochtenberg.1452:

Also recently some minis have stopped following you at all.
Evon Gnashblade, Ellen Kiel, Toxic Nimross, Peacekeeper Shocktrooper.

I’ve noticed this bug for the Toxic Nimross. The mini once summoned will not follow. I’ve been able to go the length of the minimap and still see its dot indicator in the same position. Relogging, depositing and then picking it up again to summon once more on a different character, and changing maps and modes all don’t seem to fix it.
