you need to add your new childobject to experiencelevels.ini next to the original main object

the glow is hidden by lua scripts (same scripts that pre hide forged blades, fire arrows on units)
rohan banner glow name is "Glow" check if the lua functions hide it

Ah ye, you probably talk about VirtualStore
it already caused me some issues before but i didn't had the knowledge at the time probably and was still a strange issue

now on my windows installs i always disable UAC and VirtualStore so windows no longer messes up with "protected" locations and nothing is being sent there anymore

UAC can be disabled directly into windows or the registry and virtualstore can be disabled with the group policy editor

I had that bug a looooooong time ago when i worked directly on ini.big and edited skirmishaidata.ini

never knew why it happened but the only way i could get AI working again was just to re install the game and revert to original skirmishaidata.ini (just reverting the file without re installing would not fix anything, it was really strange)

after i moved to working with -mod command and i never got an issue again with editing skirmishaidata

You use the NEED_UPGRADE like for the real button
but since the commandset will be changed when they are upgraded it will not matter
