Users can bypass timer when tick rate is lowered.

[Symmettry]

Describe the bypass and how to replicate it

Step 1. tick rate of 10 Step 2. timer of 2 Step 3. bypass timer checks; you'll go at normal rate and others will be at half rate, so you're double speed.

Also something noteworthy; if I try to set tick rates of individuals using packets they can also bypass this; so potentially any sort of API for plugins which could allow setting tick rate of a player would be nice for my server (it does tick rate things)

They still flag if they go over vanilla speed right?

This does not work on the newest ver of grim i had this bug before

[Symmettry]

Problem is if i send tick rate packets for client side timer only, grim will not know, and therefore they can use timer to bypass it.

Does this bypass still currently exist?

Does this bypass still currently exist?

pretty sure it does, we don't track tick rate
