This stuff up is another demonstration of why DLS items should not be changed to built-in. If they weren't builtin they could be easily repaired. When will N3V stop changing freeware to bult-in?
I have a similar issue with the multiplayer session for Kickstarter. It uses version 4 of JRs SD45 Engine. I updated engine dependencies (now ver6), session has "modified local assets". Remove ver6, session has "obsolete assets". Wont download on DLS because the JR SD45 used in session is Payware, but dependency is freeware. TANE install broken. Cant play a multiplayer session.
