Sorted them all, removed all false starts + server tests, there are 3 from day 2 that I couldn't get to work at least on my PC, they are:
Upper bracket finals round 2: BIGBLOKELAN v Czuraci - Snakewater
Lower bracket finals round 1 - wer das liest ist doof v Duplo - Snakewater
Lower bracket finals round 1 - wer das liest ist doof v Duplo - Sunshine
I've stuck them in a separate folder just in case they'll work for anyone else
Fixed them + some of the demos from day 3 using this and #5 in this from this thread, god bless ArchRhythm + Collaide
