This update was fairly delayed due to a trip I attended to Norway for 12 days. It was released to correct reported issues thru my inactive time. Another update will be released soon that's going to bring a big chance on how the movement checks are run and hopefully greatly minimize the performance.
Regarding the 1.13 compatibility... it will happen. Please let the SpigotMC developers work and release the official build and then it will be a matter of days for me to catch up.
