Server Version

1.21.1

Describe the bug

Without any modifications to my setup or schematics, after updating from 1.20.6 and P2 7.3.8 to 1.21.1 and P2 7.3.9 I'm getting the following error during startup. I'm running the latest version of FAWE (#879) if that matters.

To Reproduce

See description.

Expected behaviour

No error, schematic was working just fine before the update.

Anything else?

I see, makes sense. FAWE updated the default schematic format to Sponge v3 whereas your schematic(s) were most likely generated with v2. The current implementation has the format statically set (and now statically set to v3). That should be dynamically be determined by isFormat checks.

I'm seeing the same thing. I don't use schematics, so I assume it's PlotSquared's own schematic for world/road generation.

EDIT: I simply generated a new road schematic and it's OK now.

@Geitenijs Might it be possible, that you've updated FAWE in the same process of updating PS and your server?

[Geitenijs]

@PierreSchwang Yeah I did! I updated all relevant plugins to their latest version today.

Will most likely correlate to #4460

The underlying change is the schematic rework - PS statically writes sponge v1 / v2 schematics but often with the wrong extension which might be the root cause. Needs quite a few larger updates to get it running again with supporting the older formats.

This problem is happening on my server as well however I am using a template for the pathway
