Using Rift for 1.13.2 https://minecraft.curseforge.com/linkout?remoteUrl=https://jitpack.io/com/github/chocohead/rift/2c400465c7e0b5abf4e643372fbd9a7e6d39e3ff/rift-2c400465c7e0b5abf4e643372fbd9a7e6d39e3ff.jar

it crashes (Riftlin 0.0.3 alone does not crash, only with Stockpile):

Apologies for the late response. It looks like Stockpile needs to be updated for the new version, as it hasn't been updated since before Rift was available for 1.13.2. I'll try to get this done at some point within the next few days.

The Rift version of Stockpile has been retired in favor of 0.4 and later on Fabric. As such, this issue will be closed-- but, if the issue persists on 0.4 or later, please post about it!
