@weave, I spent quite a bit of time on this and if you have Studio and you copy the Android folder into the Classic October update it seems to solve the export issue, a few people have varified this.
If you don't have studio and copy the the mipmap files from the January Classic update it 'should' work at least it did for me.
There are so many files missing from the October update that depending on each individual export results may vary. The October update is a mess unfortunately and won't be fixed for a few week's at least.
If you have Studio I would use that to export your projects, if you don't have Studio I would email Orvillian @TGC for assistance

Note: regarding the bundle_temp folder, if you install the January update you will see that it also creates a bundle_temp folder, this is a red herring.
