Thank you, this was the fix for me

Just want to confirm; I'm also getting the error regarding "trader does not exist in SPT" for this mod. I'm using a 100% fresh install and have not performed any version of profile transfer, or file editing at all, outside of using GREED to modify pocket sizes, flea market offers ratios, etc. It's an almost brand new file in which I have literally completed 1 raid. I logged in successfully, exited, edited with GREED, logged in successfully, created builds, purchased from Haephastus, completed a raid, exited, edited with GREED, and got the error on next boot. However; as mentioned in someone else's post, going in to SPT>user>Profile and selecting my current profile; and then removing the "6746722bcce65386cfcc7209" line located under "Traderpurchases" resolved the issue. After making this edit, I went in. Purchased from Haephastus; exited and logged back in with no error. HOWEVER, I then decided to test this by going back into the game; making a new build, purchasing it from Haephastus, changing the magazine, adding ammo, etc, exiting the game, and then attempting to log in again (no GREED changes or anything, just a straight log out, log back in) and I DID get the error. So I am able to recreate the error by logging in, buying a gun, hitting "edit build", adding mods that I don't have by unchecking "use trade" and "use owned", saving the build, purchasing the new build from Haphaestus and exiting / rebooting the SPT server. Essentially this means deleting the "TraderPurchases" line for Haphaestus anytime you create a NEW BUILD is the temporary workaround. So if you really just have 5-6 builds you like, you can create them up front, edit the profile file, and you're pretty much golden until you create a new build. Hope this helps you fix it!

For anyone attempting the temporary fix in SPT > user > profile; open the text file exactly matching the user profile at the top left of the SPT launcher when booting SPT. (If you only play with one account, you will only see one file). Once open, “find” TraderPurchases and look for ““6746722bcce65386cfcc7209”: {}” you will see it likely just before the word “friends”. You are going to delete ONLY the line below, AND THE PRECEDING COMMA, EXACTLY as I write it below, including the {} (I will not add quotes, in order to maintain clarity), hit file and save, reboot SPT server / Launcher if you haven’t already…. DELETE ONLY THE FOLLOWING, Do not forget the comma after the {} on the line above!!! If you do, on your next boot the profile will mark as "corrupt" and will automatically be replaced with your last backup, which likely has the original error. , “6746722bcce65386cfcc7209”: {}
