I also warned only happens sometimes. 😉 (And by the way I were using a bad computer)

This computer I'm using right now is good but the 1 for 7 hours ago were my schools computer. 🙂 (Cause I'm from Denmark so our clock is different.)

I think it may be a valid issue, it seems like it may happen. However it would be hard to reproduce.

Yeah, this is very rare so its hard to preduce just 1 time.

Is the portal crossing a chunk boundary?

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

No response in 4 months, assuming no longer an issue.
