@dckc Why am I getting type feedback about ancient types?

Reappeared after restarting eslint server and typescript server. But doesn't happen with yarn lint in the relevant (contract) package.

ancient compared to what?

I upgraded the dependencies from upgrade-12 to agoric-upgrade-14 a couple weeks ago ( fbffa62 ). That's a little iffy, since upgrade 14 hasn't made it to agoric-3-proposals yet -- that's the package that provides the blockchain software we use to run the dapps. I haven't run into trouble, so long as I keep the endo package versions nailed down with resolutions.

I have recently learned that I might be able to use more recent agoric-sdk packages by using yarn add PKG@dev. I haven't found time to try it yet. Things tend to go wrong in bizarre ways when package versions change, so I have a certain level of anxiety around it.
