This bug report but simply put: Some maps get you stuck in an inescapable place when first loading a replay. This would be fine if party members could toggle noclip during replay, but you can’t. Allow party members to teleport to you when showing them a replay perhaps? (Also can chat be enabled for replay cinema but just without showing their level or something? You can only use party chat for a party of 3, which makes it more inconvenient)
Hello 
Thanks for submitting a bug report.
This is an issue we typically resolve with the maps themselves. Can you list which ones you’ve had issues with?
This probably only occurs to very few and specific maps, but that 1 Bedwars Solos castle map is as far as I know. (i believe its called arcane)
I’ve logged the issue with Arcane’s spawn point, and you can look forward to a fix in the future.
This issue has been fixed
