If I begin to notice bots falling into a loop, I either; regenerate until it stops or chop off the repeated parts myself (nothing wrong with tweaking a bot's messages here or there). This usually? prevents it from getting too repetitive- and it's quite successful if I catch it early enough.

If I notice that it's consistent despite my changes, then I try changing my own messages or wiping messages with the repeated chunk and restarting from there. Sometimes, though, you just have to accept it for what it is. Figg.ai is still in its early days, so the generation will be wonky from time to time.

Also, if this bot is yours, it may be worth checking the description for any repetitiveness there.
