Confirmed and fixed. When you arrived through a named portal we placed you 30px to the RIGHT of it - an old guard against re-entering the door you just came out of (which is already handled by the authentic warp cooldown). The Cave of Evil Eye IV landing is a ledge that spans only x=540..570, and the portal is at x=563, so +30 put you at x=593 with no floor underneath: straight through the map, every time. You now materialise exactly on the portal, which is what both Cosmic and the v83 client do.

Good report - 'possibly the spawn point is just too low' was the right instinct, it was just sideways rather than down.

(On the dev branch - it will be in the next published build, not v32.)
