Plugin's core: bukkit-v1.16_R3

Logs of the server where error occures:
latest (3).log

Player just tries to connect to the server and after interval seconds of packet alive length, user automatically disconnects even without entering the world: resetting world, without plugins and other are not solving problem.

Idea of deleting TConstruct is not a case of solving problem, it seems that RandomPatches just don't "patch" max_compressed_packet_size.

after we removed the tinker, it worked with all the necessary plugins. but as soon as I returned tinker and his addons, the problem repeats. tinker is the basis of the assembly and it cannot be removed, please take this into when deciding.
