Not sure if this is intended but I have recently discovered that if an unresearched vehicle has been moved above a vehicle you own you have to research it before you can progress… as it is the situation with my Do 335 a-1 i am not allowed to buy it despite it saying that i can further research down the line. This has all happened because Gaijin moved the Me-410A-1 above the aforementioned Do… I personally think that this change is completely unfair, I have been progressing down the line for quite sometime and suddenly Gaijin makes a change and I cant anymore. I would have to waste roughly 70,000 rp on something that I shouldn’t have to do anything about. Please if you read this Gaijin change this mechanic soon
The foldering of vehicles was just a sham pretending to lower RP without lowering RP, it just moved things around.
