commandblock2

it was kinda weird, I never see any value starting maybe with -32768 or around, it's always that giant number, is it VFP or just everyone's using the same ac? Btw I even see some server like sending 300ish transactions per second and wtf is that.

I think it would be helpful for people to have this as ZIP to drop and extract.

transactions.zip Also looking forward to our marketplace, I do know that some development happened on the branch recently, hope to see it soon.
