Hello <overdose>,
"all MODs" is just tooo much!
The manuals will be your friend!
You should just use one of the GUIs. If you acivated one after the other the last one should be the one you see - I guess it is "Six-Dials-Simfeeling".
For the SLS-MODs use "_LSH3_V5_SLS_Schiffshorn-Leuchtkugeln-Seenotsignal" with either "_LSH3_V5_SLS_Spezialeffekte-Gross" or "_LSH3_V5_SLS_Spezialeffekte-Mittel" and then append "_LSH3_V5_SLS_Sinkverhalten-SH3" if you like!
Concerning "... but I couldn't see any ship to sink" you WILL NOT BE ABLE to see any ship until you deactivate the MOD "_LSH3_V5__Single-Multi-Player-Missionen". This one is for SingleMissions and MultiPlayerMissions!!!
For your Information:
If you keep the mouse a little staedy over each MOD there will be a Quickinfo available. Rightclick the mouse and open the manuals for further information about each MOD.
You should deactivate all the MODs and then select only the ones you like to try. Don't forget to activate "_LSH3_V5" first!
Maybe you better start a new career afterwards.
