right now the modgui is not added in the original lv2 bundle.
when deploying the SDK is not checking if the modgui is on a separate bundle or not.
for now you can manually add the modgui to the original bundle, by doing (in generic terms):
mv Bollie_Delay.modgui/manifest.ttl bolliedelay.lv2/modgui.ttl
mv Bollie_Delay.modgui/modgui bolliedelay.lv2/
edit bolliedelay.lv2/manifest.ttl and add <modgui.ttl> to the seeAlso property (it’s separated by commas).
delete Bollie_Delay.modgui directory (now empty)
