Hi Propnut,
I'm glad that you finally got the best part of this game running and I hope you will enjoy the hunt in SH5 with TWoS
Your story is the cause that most modders here on Subsim are working hard in their spare time to make players enjoy SH5, a SH game that really needs these mods to make it playable.
With the megamod TWoS you are on the safe side with close to no problems when playing. However, I recommend you to read the 'Tips' section of the TWoS documents that come together with the mod. There are plenty of 'subtilities' to know soon or late as you advance in the campaign. And feel free to ask any questions here
Have fun!
