Now out of all the issues I've had, they've had stupid fixes but this one, oh boy will this one turn out to have a real stupid fix I bet... I'm really stumped as to why it's happening though and it's making my AIW progress not progress at all (if that makes any sense)... Using: Mostly fresh install (throttle blip disabled, AI strength & aggression changed to 100 & 50 respectively). -ISI Belgium '66 - Modified AIW -EVE F1 '68 -Same player.json for DevMode & Singleplayer. -Same track settings for both. -Testing Session for both. -Same AI with RCD (max stats). -AI Autocalibrate 0,1,2 (all tested). Problem: So basically I got my AIW in DevMode to the point (using Autocalibrate: 1) where... -AI were rarely crashing (maybe ~1/20 laps would have an error and maybe crash/spin) -A few of the 100% AI qualified better than me, which is what I want). Thinking my AIW was ready I packaged everything & started up singleplayer, boy was I wrong to package it... AI are all-of-a-sudden WAY off pace & they keep crashing OVER & OVER & OVER 'til they get stuck in a fence. Maybe I'll record a comparison video tomorrow, I don't have a video editor or the time & patience tonight.
