Plotting "stock.std" error.

[niafall]

I'm getting an error then running plot(fit, data="stock.std"):

Error: Column `age` not found in `.data`
Run `rlang::last_error()` to see where the error occurred.

Similarly, when running tmp <- plot(fit, data="catchdist.fleets"):

Error: 'vec_as_subscript' is not an exported object from 'namespace:vctrs'
Run `rlang::last_error()` to see where the error occurred.

I installed rgadget at the end of last week, so it should be up to date. Perhaps it's another package problem?
