watch mode does not recover after error

[dgrammlich]

I use Buchungsstreber 2.8.0 with YAML format.

I started Buchungsstreber in watch mode. After that I started it in a second terminal in edit mode. It is configured to use ncalcli and resolve the incoming dates via regex to template identifiers. If one of the dates has no resolver or identifier, this error occurs:

NoMethodError: undefined method 'valid_activity?' for nil:NilClass

It seems that the lines with error messages move the other content up and out of the window.

In edit mode I remove the conflicting date and save the file. The watch mode still shows the error, even after I press ENTER to reload it manually.

Starting the watch mode with a valid file seems fine.

Maybe seems to be related to resolvers or generators? Since an uncomplete entry

  - 0.5  # TODO

looks like this

Bitte einmal vollstaendigen stacktrace via:
