It looks like development on this was never completed? Sad :(
I tried for a while trying different random seeds just trying to get one with both bot types to be 216, since at least then they would be usable. Couldn't find one.
I "fixed" this by installing an additional mod pack:

This doesn't truly fix anything, but what it does do is uses 6 tiers of each bot instead of just 1. 3 of the tiers come at the same time or earlier as the standard bots. This gives 6 random rolls instead, and so I was able to find random seeds that would have workable bots at enough tiers to be usable even though ~2/3rds would be rolled as 0 kph speed.
