Delirium index exploit?

Could be a bug or normal. At Easy it seems plausible to have 1% in first parts of middle game. In general delay this research gives no guaranty, I did it and hadn’t ODI at 1%.

Try I don’t remind if it was a research requirement, I believed it, but not sure.

According to this thread, it is a requirement for PP end:

But eventually the player didn’t bother counter check without research ODI. Myself I tried counter check a few final elements, and it gave nothing the requirements was right.

For other ends, I think it will block them too if it blocks PP end. That said, it could be delayed a lot even if a requirement for ends.
