@Jimbohalo10 I have admin rights already and also veryfied the installation a few times. The login problem is not my main problem - that’s only sometimes. The main problem are the cases 2 and 3 I posted. ---

Hey I’ve been getting network failure on 2 maps, they launched after a fresh HLOD build. I changed some things that were not in the HLOD and thought I could get away without a rebuild, but maybe they need a fresh rebuild at least after UEFN updates, at most after any changes. ---
