OSM-API rejected JOSM upload: Placeholder node not found for reference -534 in way 27712090

[phobie]

After doing some bigger landuse edits I tried to upload my changes and received the exception shown below.
I deleted the problematic way and tried to upload again.
This failed also, but with a other way...
