Mechs Vs. Minions: Card Corrections

Mr. Piddlesworth stated: later printings will have errata corrected. I know rule books get updates all the time. However, my question is if cards get errata corrections, will the people that bought wave 1 be able to get the updated cards? I saw a YouTube video that said the cards might need some changes. Example: One card at level one stated that you "Must" turn your Mech 90 degrees. However, the level 2 of the same card did not state that you "Must" turn 90 or 180 degrees. Also, will we get a PDF file with errata corrections for the rule book?
