Can't research 3D Graphic LV2

Hi all,
game dev tycoon is a great game, thank you for made this.

i have a problem with research.

I have 3D Graphic Version 1 at level 6, but i can’t research 3D Graphic Version 2!!!

why?

Does the research tab have the option? Or is the option there but it isn’t working?

I don’t have the option…

I’ve now start a new game and 3D Graphic Version 2 has correctly become researchable after i reached level 3 with V1.

Confirmed. I’m in Year 20 and 3D V2 is still not available for research. But it did only happen once.

Cheers

An update: As mentioned above it turns out you have to develope some games with 3D V1 to unlock V2, so it is no bug.

I never had that sort of error with it. From a gamer prospective, its wise to save your game constantly then go back to that saved file when you approach a bug in the future.

I have develop A LOT of game with 3D Graphic V1, in fact it was at level 7 before i quitted that game and started another one. If it isn’t a bug i don’t know what it is, but actually in the new game as soon as i have reached level 3 with 3D Graphic V1 i was able to research instantly 3D Graphic V2…
