Managed to open game.
1. Open
Users\Your User Name\AppData\Roaming\Stencyl\stencylworks\games\Your Game Name\snippets\list.xml
2. Comment out snippet by snippet and try to open game - repeat until it opens.
Now I'm getting weird errors on compiling(fkd up brackets):
event.otherActor.applyImpulseInDirection(Utils.DEG * (cast((scripts.Design_40_40_DistanceandAngle._customBlock_actorToActorAngle(actor,event.otherActor)), Float), 35);
Logs attached
