Checklist

• [X] I have included a Fawe debugpaste.
• [X] I am using the newest build from https://ci.athion.net/job/FastAsyncWorldEdit/ and the issue still persists.

Anything else?

fawe-demo.zip Here is the .schem file I used to verify this issue.

Seems like you are using the Beta version of WorldEdit 7.3 to create the schematic, which will be written as v3 by default. You can use //schem save mySchematicName sponge.2 to use the v2 format. FAWE should be able to load that.

We'll keep this issue open until FAWE supports the v3 format.
