So preserving salt only has limited utility right now. Wyvern milk, leech blood, ammonite bile in preserving bins is by far the best. Current a stack of salt lasts 2 hrs.
First suggestion, it is my suggestion that all of the decaying resources (leech blood / ammonite bile) should be able to go into the fridge. My leech blood spoils for fishing.
Second suggestion, Preserving Salt (which was a godsend in Structures plus) should be placable in fridges and both benefit and slow the decay of items in the fridge. It can save my tranq darts?
Final Suggestion, perhaps there should be a priority recipe (gets autocrafted first) of adding Preserving Salt to the jerky production at a faster rate. It currently takes 36 minutes for meat to convert. What if we reduced its by 30% if we craft it with Salt. A 24 minute craft time might make it worth while to farm.
