There are a lot of mods that implement Crossbows in the world on NPCs and through item leveled lists. For those using Creation Club Expanded Crossbow Pack and Elite Crossbows mods this means if you want to properly integrate all those (new) crossbows in the world it's a lot of patchting work. I got tired of it. So for my SimonRim oriented mod list I opted for a conflict free and vanilla-esque solution that at the same time fixes the balancing problem with Creation Club crossbows: all of them are only sold by the Dawnguard vendor, just like the original crossbows were.

What this mod does:
- creates SimonRim / Thaumaturgy enchanted versions of all crossbow. Thanks to the mod by Teylahime.
- distributes those crossbows ONLY to the Dawnguard vendor, Sorine Jurard in Fort Dawnguard, just like with vanilla crossbows. She will have an assortment of (enchanted) crossbows for sale based on your level (just like regular Skyrim vendor, but for crossbows). Thanks to the mod by EternalRaven19. 
- rebalances the crafting smithing requirements of crossbows to be in line with SimonRim.
- in vanilla crossbow crafting is limited to the Dawnguard forge, an optional patch makes crossbow craftable at any regular forge. 
- Disables the Creation Club quests scripted item injections in leveled list and removes the overpowered gear the can be find through those quests. You can only find crossbows at Fort Dawnguard.

My mod combines Teylahime and EternalRaven19's mods and heavily edits them both to fit my vision. Thanks to both of them for having open permissions.

Please let me know if I made any mistakes, they should be easy to fix. Advisable to use this mod on a new save since the creation club scripted injections cannot be retroactively disabled.
