Some of the earlier added research bonuses have some unusual costs, such as 2b which seems to cost 70000 military research packs. It might be cleaner and simpler if you used infinite research options which scaled in similar ways to either the miner productivity or the robot speed. It would also clean up the interface to do this, since you would have one continued column of research instead of 7 branches in the research tree.
Thanks for working on this!
