Description
Put A Plug In it! (PAPI) initially solved a Memory Leak I found with Sophisitacted Core while playing the "NightfallCraft - The Casket of Reveries" Modpack by P1nero
Sophisticated Core natively fixed the Memory Leak in their 1.20.1+ Forge & NeoForge versions, but the pre-1.20.1 and Fabric versions of the mod still have the glitch, which PAPI can be used to fix.
PAPI now also aims to find and solve as many Memory Leaks as possible, and integrate features and compatability for and from other mods, to make an all-in-one Memory Leak Fix and Memory Optimization mod, and to increase version and loader support for features of other Memory Leak Fix and Memory Optimization Mods.

Icon and Name by lyftos, inspired by Plug & Play by Morio von Rickenbach, and Michael Frei (Playables)
