Hi BloodWulfe,
I am sorry to hear you have been hit with the MD5 error, and I completely understand the frustration this error can cause. I also must apologize if I was the creator of the MD5 thread you mentioned. The confirmed post which I update when I have new info is here -
https://7daystodie.com/forums/showthread.php?50175-Known-Issue-Terrain-Rewriting-(MD5-Issue) which contained an edit. However if there was another announcement post from me with inaccurate information please do link me to it so I can edit it. I am sorry if you have felt mislead in any way.
For the MD5 error, if you are playing on XB1, there is a player found workaround which sandman (thank you!) mentions in their third post. The original post about this can be found here -
https://7daystodie.com/forums/showthread.php?69218-Possible-work-around-and-or-solution-to-md5-crashes(base-wipes-resets) - As this is an unofficial player workaround that involves deleting and resyncing data, caution is advised. While I understand this workaround is not ideal, many players have said it helps them avoid MD5 errors.
The other two suggestions Sandman mentioned about are also reported by a number of players before the resyncing workaround to have helped them avoid crashes and potential MD5s.
If you are finding your game is lagging a large amount before crashing, and it's in the same area, there are some items which can add to the lag. These include large amounts of toggle lights, torches, candles, a group of growing trees / tree farm and woodframe windows all in the same area. Consoles in bunkers and power stations also seem to add to this. Reducing this items may help reduce any excess lag that may speed up crashes.
As Sandman mentioned above, there are multiple triggers for the MD5 error. While the team have fixed a lot of them, there are still some triggers remaining that are a little more difficult to fix. The team have not given up though and are still working on the issue.
Can you tell me if you are experiencing the MD5 being more frequent since the 1.0.18.0 update? Is it centered around your forge / crafting stations / storage area?
