Persistent Move Speed Bug - Either Slugs or Water

[12 Hatch]

After a nice swim in the large "to some island" underwater zone, I experienced permanent movement reduction that no amount of resting, relogging, antidotes, or restoration would cure.  It was either due to the water slowing, or the multiple slow bolts I ate from a few irritating little detritivore slugs.

So, one of those two caused this persistent run speed loss.

Yeah this has happened to me after swimming somewhere else, I imagine a reset will fix it or a DM killing and reviving you works.

I've just had this bug occur as well - yet I've been under the same circumstance as the op before and not had this happen.  Very odd.

Simply just returning to the underwater area for a moment fixed this for me.
