Ow! Got the suspected bug today, first time. Also first time using research bonuses since updating to the release version (it was a clean install I had zapped the Beta first). No idea whether or not ability research bonuses were a significant cause.
One thing I did notice was it happened when I had reduced the Production Slider to 60%. I'd had a rush of enthusiasm at the two game year point, and expanded too fast, dumping colonies everywhere. Cost spiraled of course, and I paid the price, having to reduce production to pay for it. I recovered by concentrating on cash generation, but noticed after getting back to 100%, the tech values were still horrible. An observation, no more than that at this stage.
I'll restart without ability tech bonuses, see what happens.
Its weird, game started fine, played well for a couple of game years on Immense, then suddenly, boom, kiss of death
Regards
