I am not sure if this is new or working as intended or if this issue has been reported in the past, but I reached level 23 on my Alchemist today and took Draconic Heritage I in Draconic Incarnation. Part of that core trait is Eschew Materials for spells without special components. Afterwards I went to Fred and swapped out my level 3 feat (Eschew Materials) for Empower Spell. Went to run some content and found I could not cast Goldskin or Elemental Combination without Alch-6: Bars of Fool's Gold, nor could I cast Greater Evolution without Alch-5: Bottles of Quicksilver, but I could cast Multivial without the component. When I had the actual Eschew Materials feat, I did not need the spell components to cast any of the spells I used. If this is working as intended, perhaps SSG could update the tooltips for Alchemist spells that are considered to have special components (even though no such special components exist)?
Another one would be partial hireling contracts disappearing when withdrawing them from the character bank and ticking down in a shared bank.
