Ways to turn of a repeating_cb set to tp you away from it [duplicate]
To solve my problem I traveled to the edge of the unloaded section. Activated a repeating cb with a fill command set to replace with air. Opened my map to lan and used the second player to trigger the tp and load the chunks.
Another method I used was to travel again to the edge of the unloaded area. Use the fill command to add activator rails and a minecaft with command block and pushed this into the unloaded area with a fill command active.
I added both methods as they both worked and many people may not use the lsn feature.
