Weird problem - custom subpanel suddenly doesn't work

[GameboyRMH]

I have a customized subpanel with a detailviewlink on one of the fields, which was working fine until I uninstalled and re-deployed the module about an hour ago, now it's as if there's no link at all. The code involved in the subpanels and relationships is the same as before. Any ideas?

Found the problem - I'd customized my deployed custom module in Studio, then uninstalled it, but some folders containing the studio customizations were left behind in the custom/modules and custom/extension/modules folder, so when I re-installed my custom modules, these customizations overrode the code from custom/modulebuilder/packages/<packagename>/ resulting in a GREAT deal of confusion and about 4 hours of wasted work time
