Okay so I'm playing on 1.12.2 and I'm using version 2.0.0.1 and basically when I'm size 1/16 and I walk towards a block and I pretty much can't go any further towards the block. I basically stop moving when I'm 3 or 4 pixels away from the block. Hopefully my image works. This is my first time using GitHub and making a post like this but if you can see it then it shows where it stops me moving. I want to stay on this version as I feel like updating will have the same issue since I used to be on an updated version but then downgraded (both versions were on 1.12.2, downgraded from a newer version on 1.12.2 to an older version on 1.12.2). I've been playing for the past few days and it's been working just fine until today/last night where I started to collide with an invisible wall. Hopefully you'll be able to help me find a solution without having to update. Maybe there's something in the config I need to change? Apologies for the awfully long post
