To be more precise, Mama's solution with
TWoS, Sobers modlist, and Sjizzle's Magui based megamod will be necessary
only when you're expecting campaign transfer, on campaign ending. Before that date, you can load your gamesaves
with or without setting OSI.exe priority, there will be no significant impact on campaign progress. And that is all...
EDIT:
Anyone else who plays
stock SH5 (forgive them God for their ignorance
) or with
Open Horizons v2.5 only ( and without
No Stupid Tonnage Bar/Free style campaign addon) will have to use Mama's solution
every time the game is started (annoying, but nothing we can do about it).
However, these players will
still experience a whole range of different issues with their objective activation and campaign progress as a consequence of certain game limitations.
