Weather and marks on map

[Michael13]

Hello.

I have two annoying issues:

1. Weather don't changing long times. It can be medium fog and 15 m/s wind at same direction for a week. And even if it's changing - only a little (for example, to light fog and 10 m/s wind, which will save for another week). But at same time save/loading usually changing weather greatly from calm sea to storm and back.
I heard Environmental Mod by W_Clear should change it, but it conflicts with Magnum Opus mega-mod. Is it installed there already? And if not, can i change files without CTD risk?

2. And second issue is that all marks (sunk ships and which i added myself) on map dissapearing after loading game. Any way to avoid this?

P.S. I have only Magnum Opus, Anti-lag and Enhanced Funel Smoke mods.
P.P.S. Sorry fo my english
