Alright, apparently game updated yesterday / today according to this
patch and it's build v1.0.0.314 now and i confirm everything still checks out fine even with my colleague
@MrAntiFun checked out with rests of DLC standalone. So let's keep straight something, i know mostly of you keep saying "not working.. " or something like that which we often ignore feedback like these but i suggest to narrow down and explain with details what exactly doesn't activate and how did you exactly activate them (and reproduce if you found so)?
Keep in mind, all these 3 trainers are mainly used only working with DX 11.
