Roblox Game Client using 14 GIGABYTES OF RAM

I loaded up a game that I work on (T.A.C Alaska Facility).
It’s really unoptimized so it froze, I pressed ALT + F4, nothing.
I decide to open task manager: to end the task.
Slowly but steadily, it memory leaks to 14 GIGABYTES.
Also, the window had disappeared, and if I were a regular non tech savvy person: I would’ve thought that it just crashed: NOPE! Running 14 gigabytes in the background.
