New Update?

i was just prompted to update my unturned, Does this mean that the 2.1.3 hacks have been patched?

Do you mean update 2.1.2, because it updated to 2.1.3 last night. If so, most likely yes they are patched considering the changelog says
-Improved anticheat verus speedhacks.
-Improved anticheat versus fake cars to prevent lag.
Now if you are using a modified Assembly-CSharp.dll it will just downgrade your game to the version the Assembly-CSharp.dll was meant for.

Ok, Thanks very much for the help XD
