In-defeatable bot..,

I’m using the SLR in the current Championship SD, with a live racing low PP high EVO set up running 12.1x just to see how far I could get. Got over 1000 trophies, then started losing to the more highly built T5 cars. Then, as I went down to about 900 trophies I started getting the same bot in a Monza running 11.4 every time. I’ve done about 5 or 6 races now and just get that same bot. Has something similar happened to you? Is this a bug?
