I don't know if it is a test-patch-specific bug, but I've seen this only in U22 and in one particular place.
When user's car in replay or in-game is in one corner on sector1 (see the attached image), LFS freezes and makes very heavy load on CPU: nothing works, 100% occupied, Alt+TAB doesn't work, neither Ctrl+Alt+Del can help: seems like the program manager just can't run because of the heavy CPU load. The in-game synthetic sound plays the same tone all the freeze time. This continues about minute or two, then LFS "unfreezes" and in-game time has passed further (in replay) or your car stands at it's start position (in game). Then everything goes on normally, if you pass that turn again, nothing special happens.
I've seen it only twice and don't know how to reproduce it. Once it was an SPR with only 1 BF1, another time it was practice session against AI, all in BF1.
