I can't verify that this is a bug due to the nature of the randomness of receiving blueprints. But I have earned 13 blueprints with Konstantine and haven't had a single chance to earn a Tolchok. Now by my math, there's only a 0.51% chance of this happening over 13 blueprints.

11 of the 13 were o.shtorm
I will update as I get more blueprints

14 blueprints.
12 o.shtorms.
0 tolchok

[xXGigglesXx]

15 blueprints
13 shtorm
2 smerch
0 tolchok
Only a 0.22% chance not seeing a tolchok after 15 BP's

16 BP
13 shtorm
3 smerch
0 tolchok

[xXGigglesXx]

got blueprints #17 & #18
Both were O.shtorm. That puts me at:
15 shtorm
3 Smerch
0 Tolchok

Got blueprints 19 and 20.
Finally, after 20 blueprints! I finally got another tolchok!

Programmers, please please please... If you could just add some code to avoid getting the same blueprint 17 times in a row. That was the most disheartening thing about this game so far.
