Here is a workaround to get around the bug in R7B3.
Workaround to R7B3 Fog Turbine Bug
If you play R7B3 and get near the end of the level you will encounter a “Fog Turbine” followed by an exit run.
We had big problems here with the “Fog Turbine” because it didn’t displace the fog and we thought that would be the end of the round.
with the multiple deaths we always reset at the checkpoint until the “Fog Turbine” worked.
Apparently it’s a random bug.
It is best to always play with a bio-tracker in the run. If the workaround doesn’t work.
