The Thioseptal can easily be lost by new (and old) players at the CSC hospital encounter as it is included in the medical items sold/donated. Possible modifications to work around this issue are:
- exclude it from list of medical items bought
- use commodities exchange / donate item screens instead so the player has control over items being traded
- add option to get one more from Huari
- add a warning that a unique item is being lost
Ugh, this happened in my current game even though I knew about it.
A quick fix would be to exclude NotForSale items from the list.
But really, a better solution would be to create a tag or property like QuestItem that prevents the item from being sold or donated to any station. This would also be good for the stargate control rod, since if you sell or donate it, the only way to get it back is to destroy the station.
Should filter by attribute.
Fixed in 1.7 Beta 6. I've added questItem attribute to several items and the CSC hospital checks for it.
