Perhaps instead of rushing out a release FL should spend more time in editing and proofing; I recall the playtest was quite rushed, with changes happening almost till the very last minute, or so it seemed. Heck the Advanced Combat was added quite late in the playtest almost as an after thought.
My beta-log say that I got the first draft December 2017. We had our first beta-test session January 14 and had our last beta-test session July 8. We managed 13 sessions during this period (each about eight hours long).
I can see the message where I asked my brother to print out two sets of combat cards before our first session so that means that the combat cards was there for our first session.
The changes to the 2nd printing are all very small. The biggest ones they made an errata for. Sure there are some more but I can't say that they are that many or that big either. Most are just clarifications. Most of these was things that FL had already cleared up and answered in this forum. In our group we have played with most of these things on this list since a long time (except for the pure changes, such as the NPC and WP).
