Update 3 on the Script_Scheduler frame drop bug

Do I really need to explain what I’m experiencing? I made two reports on the same bug all as an update to each other, and it is still happening. You guys haven’t fixed this at all. What this bug does is that something is causing the script_scheduler to go into an infinite loop without a proper way of dealing with the byproducts of it, and this then leads to it spiraling out of control after 20+ minutes of the Roblox client being open on my device which causes me massive frame drops, and slowdown which can last from a few seconds to even a full 10 seconds because my CPU can’t handle the load anymore. This obviously causes extreme CPU usage which is what my original bug report reported on. I even have stream clips of this bug recently if you want to see. I even tested it with the unmodified Roblox client, and it still lagged.

Have you guys found the direct cause for Script Scheduler going out of control?

HOLD UP this is promising

No, this does not fix it. Like at all.

Bumping this so more people can be aware that this bug is still happening even after the Release 735 update.

Another bump because we need Roblox to fix this.
