Yup, very common. I’ve heard this explained as a network issue. The “server frames” are getting dropped (or not syncing) and the player location can’t be synced. This is the one where your character continually jumps back to the spawn position everytime you attempt to take a step. There’s another form of “being stuck” that has to do with collision detection: Getting stuck on a bush, a mount’s saddle, inside a foundation or etc.
Not weird - fairly common, especially with high ping connections or busy networks. It //usually// remedies itself in short order - but can often take “too long” - whatever that is to you.
