In my TTT server random players run/walk speed will decrease randomly.

Hello people,

Recently and out of the blue, random players in my TTT server will start running/walking extremely slow at the start of the round. I have re-installed our advanced TTT and looked through all my files for maybe a new add-on that could be causing this but found nothing. Any suggestions?

New development. Randomly, players with jump pack will have close to no gravity at random times…
