Notes (Required)

There is an incompatibility with this mod and Tinker's construct (It is confirmed that this mod, as in Diagonal Windows is the culprit, and that it specifically happens with Tconstruct, although it might happen with other mods too). I will leave a link to the Tinker's Construct's Github page in which this issue is detailed, because I think I do not have the capability to correctly explain what is happening. The result is that Minecraft uses too much ram and takes a ridiculously long time to load into the main menu.

Edit: Just in case, the comments that are going to help you identify this issue are at the bottom of the link I sent.
