As a player, I used an ad portal but did not teleport and could no-longer control my character. This did not resolve until I closed Roblox.
In Natural Disaster Survival, I saw an ad portal for a game in the lobby. When walking my avatar into it, my screen went semi-dark as an effect while teleporting. The experience continued playing in the background but I could not control my character.
Client console:
Later, I tried to reproduce the bug. I saw what I think was the same ad portal in NDS. This time when trying to enter, it gave me a teleport failed UI prompt but didn’t semi-dark my screen and could move just fine after failing to teleport. I don’t know what was special about my first attempt that caused me to get in a locked state.
Either way, teleport ads should not be presented if I cannot visit them.
