Should be fixed, hopefully they don't restructure the API for popups again again.

Been awhile since I checked on this mod, looks like one method got deprecated and another got switched around, should work now.

Got an error

I've decided to start figuring out how abilities and stuff work, so I've released a mod very similar to this one that instead gives you an active ability that you can use to obtain data disks at the cost of Skill Points repeatedly without arbitrary limits like this mod.

Sure why not.

Just a quick question can u do more? In the "character" late game most of the time i have every skill and i dont know what i should do with my SP. I mean in the Tags its allready a Cheat sooo.

Absolutely must-have if your character is going to Tinker.

Should be fixed now, today's update added another parameter to the Popup.ShowOptionList method I was using.

None

It isn't precompiled so you can just open up the mod files directly:

RE: my below, no promises. This would be me dabbling. But I am curious!

I don’t suppose you have the source for this on GH? I wouldn’t mind taking a look to see how much of a PITA it would be to handle the edge cases, e.g., de-duping results, only allowing additional Research levels if more unlearned recipes exist, etc.
