I ran into a very interesting issue when I was taking a town portal back to the Echo of a World after completing an echo. I went to the End of Time, and then there was a blue portal with the name of the echo map I was in. I’m not even sure if this portal should have spawned, but due to muscle memory I just took it without even thinking.
I ended up back on my Echo (even though I had actually completed it and was in the Echo of a World before leaving), but my character didn’t spawn. I had no way to move, but I could open another town portal. Unfortunately, I was not able to activate it. In the end, I had to return to the character select screen to fix it.
Below is a screenshot of what happened after I took the town portal.
