Unfortunately, there isn't anything I can do to prevent the client from firing early. Clients do not run server scripts.

A way to remedy it would be to force the exact frame the client should be at compared to the server. We have had similar issues with this before and requires a lot of design, so this will not make it into 98e.

I do propose an idea to solve a lot of these timing issues that are related to scripts. Perhaps people who are scripting need to make code specifically for the client-side to handle bugs such as we are getting. For example: In setweapon_01.wad you could have a function that runs server-side and a function that runs client-side. Both functions are nearly identical. The client-side function is to predict what will happen, in this case, SetWeapon. Doing so could prevent issues as what we are getting.
