I can't remember if this came up before and I couldn't find it in the patch notes - the OKW Schu mines don't deal suppression (unlike their equivalents in other armies). Bug?
This has been fixed to the extent that it's possible (teller-like early detonation).
Relic has put up another (final) survey for you guys to vote on.
The result of this survey will determine the final state of WBP, at which point things will move over to the implementation phase: https://www.surveymonkey.com/r/WBP18
As a clarification for question #7 Anti-tank capabilities also includes the Satchel that 1.8 Penals have.
Stop trying to get everything perfect and just patch the fucking game.
There will be no players left by the time the patch arrives.
Even if the patch were ready a week ago, there are certain scheduling conflicts within Relic (i.e., the crew that will take care of the implementation) that mean there would practically be no difference in the release date.
