I’m going in circles. Game won’t package for errors that won’t let up after trying numerous things per forum post, e.g. Fix up Redirectors via RBM Content folder, rebuild in VS, delete Saved, Binaries, Config, forget the forth cache folder, the first error I’d like to focus on relates to a plugin, iLocalPlayer, used to support SideBySide output that I no longer needed, disabled it, deleted any related assets, first within Editor, then at the directory level, alas a reference must be persisting in cache. I tried migrating to a new project, but the same error persists when cooking or packaging. So vexing, many thanks for throwing a bone.
