Functions / Scripts break in Team Test and In Live Game

Functions, Systems, Scripts and more break inside of Team Test and a Live Game but remain perfectly fine in Solo Test + Local 2-Player.
A friend and I are working on a Group-owned game. Recently, when testing in Team Test or playing in a Live Published Server we notice several things felt „broken“.

Things like Animations, Scripts, whole systems no longer seemed to work.
Server logs were completely empty and unresponsive, Client outputs infinite yield errors.

We haven’t made major changes recently and these exact features worked fine in previous test sessions. Our last Team Test session was about 4-5 days ago, no issues during the time.

I can also confirm again that: (Test Solo) and (Local 2-Player Server & Clients) Works flawlessly as intended, so no problems there.

What exactly is happening here?
Has this or anything similar happened to someone else before?

Team test has historically been broken even for working live games, I would not test in there but it’s been a while maybe they’ve fixed it. For live breaking when it works in test, that can absolutely happen because assets take longer to load, there is actual network latency (you can simulate it in Studio but I doubt you have that on right now), etc. Can you please show me just one system that breaks in live servers?

Sure, this is the main local script for a movement system, Under starter character. It was an open source system, then modified to fit our game and had always worked without error, regardless of the environment. Specifically the Running function no longer seems to work properly, like it just stops working entirely.

At the time of writing this, My friend has rewritten and edited some parts of code from functions that previously broke and it looks like it has partly fixed things, but no idea if thats a temporary or a permanent solution. These edits were not made to the code below, and the Running function still doesn’t play properly.

Replace getHumanoidRootPart with

return Figure:WaitForChild("HumanoidRootPart", 2)

Tell me what happens, although this is just a guess. What happens in the console? Does an attempt to index nil with Velocity (or any other property) error occur

No errors relating to the movement system, and the running function actually appears working again, tested on a mobile device in a Live Experience, Not Team Test. So this is a issue related to character loading? Thank you for the assistance so far :sweat_smile:

Great if it works you can mark it as a solution, and yes it does seem like you were trying to index HumanoidRootPart before it loaded

This goes for all systems; you are probably indexing stuff before it loads. Use wait for child
