Suggestion (Required)

When playing with high latency it becomes very apparent that the speed effect from blocks is handled as a server-side stat, as the speedy effect can appear to occur much later on the player's screen than when they touched the blocks.
Understandably this might not be an easy one to solve, just thought I'd put the suggestion out there!

Do you have this issue as well with vanilla's soul speed enchantment when walking on soul sand / soil? Block Runner uses the exact same method, so it might come down to a vanilla issue after all.

I made some small changes which could potentially fix this, but I can't properly test if the fix was successful. Either way this seems to be the best I can do.
