Problem with build and export in Scenery Editor - how to debug and verify the build?

I’m opening an airport project that has worked perfectly fine back in December
in Scenery Manager. I edited some terrain (no new or changed models) and I’m
trying to build a package with a new “Build & Export” option. However I don’t
get a zip file in the Export project, and while some package files are
created, there are no more successful build confirmation in the console. I
can’t even find if there were errors on my part. Even if I do “Clean All” All
I see is this:

PackageBuildLog_G AddKey wrong key :PREPARE
PackageBuilder | Done, 7 asset groups registered.
PackageBuilder | Failed to find asset group for file D:\MSFS Projects\CNC3\MARKETPLACE\EXPORT.ZIP
PackageBuilder | Partial build : nothing to do

Among thousans of lines of unrelated code in the console. Many lines,
especially in beginning, are also completely screwed up with the beginning
words truncated, so I can’t be sure I’m not missing anything. How can I know
that the build is correct and complete, and why is ZIP not created in the
Export folder?
I can’t update all 3 of my projects because of this. Advice
appreciated. I have the latest 0.14.0 SDK and latest hotfix on MSFS. I’m
attaching the log file.

Hello Roman Several issues here. - Have you switched the console group to
“Builder” to remove all unrelated loading messages? (see image) - The partial
builder error is caused by your export being done in your project folder. The
package builder system detects a new resource has been created and tries to
identify its asset group type. This shouldn’t be a problem preventing you from
building and exporting the package. - Can you clean your console and just
build your package with the builder group selected and tell us what your log
is now containing?

I did exactly as you told me, plus I selected a different export folder that
is outside of the main project folder. I selected BUILDER group and cleared
the console. Still in the console, in the builder group I get many unrelated
message, and most of them are truncated so it’s hard to make sense out of 887
lines of mostly truncated text. This form is not big enough to includ, so I
will attach a text file with the log. This is the first “build and export”,
after “clean all” with Builder group selected: This is the second time I try
the export - this time the log doesn’t make sense at all: lines are truncated
and nothing seems to be related to the build itself - can it be that it got
truncated with the rest? Export.zip gets generated in the Marketplace folder
under the location I selected for export. But I have no idea if it’s a proper
build, and if the build was successfull. What are the messages about Asobo
B787 and liveries doing in the Build group? I’m not using anything like that
in the project, just a few generic Asobo GA planes.

You shouldn’t have those community packages message in the console when the
build group is selected. It’s also surprising that the console is not giving
any information about any build step or your CNC3 package (the one you’re
building and exporting, right?) I guess that’s a consequence of the message
queue corruption. I’m still trying to repro this, I had it a few times but
it’s tricky to fix without a reliable reproduction procedure.
