Hey _CodeGreen, sorry to bother you, i have found a problem that, i think, is caused by your awesome mod.

The problem is that if i research stuff at some point it just blocks the next research that should be available, for example i have a mod installed named "Black Market 2" and i can only research the first 2 or 3 techs in the the tech tree after that it just doesn't let me start next tech research.

I already tried a differend planet start and it still didnt work.
But when i startet without your mod it worked just fine and i could research all the stuff i wanted

I have a bunch of mods installed and i guess the problem lies in the tech tree arrangements that you do in your mod, since some other mods do the same they get in the way of each other and break, well thats just my guess since im no expert, that why im asking you (the expert in this kind of stuff) and hope you know the reason

Best Regards
secretus

PS: sorry for my grammar errors or mistypes, english isnt my first language

I haven't inspected Black Market 2 specifically, but I did just release an update that makes removed technologies correctly handled on my end. I don't know if it fixed the issue, but what you've described sounds like it was a symptom of the previous method. I believe it's fixed now in version 1.1.0 and up, if there's still an issue feel free to let me know. Sorry this took so long!
