Thanks for the comments once again, and @Luminusian: the joint limit is the maximum number of times you can change the state (Hold/Relax/Extend/Contract) of a joint in a single file. If you go past that limit you can't save your replay, and if you add in the rest of your movements into the same file by hacking, it'll glitch.
When doing a 500 frame replay you don't need to worry about it and that's why lots of replay-makers aren't aware of its existence, but when doing more complex replays like the spar or the freerun I posted it's easy to reach that limit.
When this happens you can either finish the replay there or continue it in a another file, linking both parts by copying your last movements on the first file to the second one, which makes it a lot less enjoyable to watch and harder for videomakers to record.
I don't know why this restriction exists since I'm clueless about programing and how the game is coded, but removing it would be in my opinion a great improvement for future versions of the game.
Uploaded again "Positive Tension" and its mod because I decided to make some minor changes to the last building relevant for the future.
