Tech Researched does not match Tech specified

There is a clause in some treaties which would explain why you are getting the AI tech and not be a bug. It is also possible to agree to research stopping clauses which will reduce your research to zero regardless of other settings if you agree to them.

Start the game again and check the treaty and be warned the AI likes to sneak in clauses banning research.

It is also possible that you have been sabotaged by an AI empire as espionage can increase research times to tens of years

Hope that helps

The first time it happened to me I thought it was a bug as is was in the initial demo. just watch the AI it might not be as good as it could be in some respects but it is devious from time to time. This being one of those times

There should be a big red flag on the research window that clearly states all research is currently disabled due to a treaty.

I would agree with that or a least something in the galactic news thing saying something like "sire you are a twit you have agreed with the to suspend all research" the same sort message should be generated by the no Intel clause and the no other treaties clause but of which are as annoying if less devastating. Persistently refusing a treaty has got me into at least one war I was not ready to fight for example

You could always try to offer a counter-treaty when the AI sends you one with a No Research clause. I did this in one game where the AI started out with a normal treaty where we shared resupply, repair, and traded research (equal level), 2 turns later they offered one that would prevent only me from researching anything at all. I sent back a counter-treaty without that stipulation and changing our shared research to 4 levels old. I guess the AI got kinda nervous at the rate I was researching weapon levels

That’s what I do now doesn’t always work though and one has to read every treaty and not just pass them on the nod in case of some such clause buried in there. Amendments also require AI agreement which they don’t always give. However I don’t mind that SEV is not a good game for people who don’t pay attention
