One time I loaded a save that included bot events. Right before I saved, i didn't finish one of the events. I was going to make its hand chance colors, but i only got this far
OnBotSpawn>Bot
When i clicked send or whatever, it finished it automatically with the events to kill the bot.
OnBotSpawn>Bot>kill
It lagged so badly, and it also made it start to fade. It lagged because of the endless loop of the bot dying. I'm so happy that i was able to find the spawn. That could be your problem, do you have bots in the save?
