Red line that hugs the pink zone erroneously gives error

[dreeves]

Replicata

1. Create a do-more goal with 30 days of initial safety buffer
2. Add a datapoint of 1000
3. Go to the graph editor (doesn't matter which) and make the red line be flat for 3 days, then jump to 200, then be flat for 3 more days, then jump to 600 and end. Specifically, we want a graph matrix like this:

2020-11-19, 0 (tini/vini)
2020-11-22, null, 0
2020-11-22, 200, null
2020-11-25, null, 0
2020-11-25, 600, null (tfin/vfin)

Arrghhh, I had it! But I can no longer replicate it. :( :(

(Pretty sure there's still a bug here and would be awesome if we could get replication steps next time we encounter it...)

• https://github.com/beeminder/beeminder/issues/1643
• Different off-by-one error with akrasia horizon #258
• Can't extend flat spot past the akrasia horizon #232
• Graph editor won't allow goal to end sooner #196
• Graph editor failing most goal changes at the moment because of Rails 5.2 upgrade thing #261

Verbata: easier within akrasia horizon, pinkzone, pink zone, no-zone, verboten zone,

This continues to happen sometimes that changes to the red line that don't visually intersect the pinkzone and that the graph editor itself doesn't complain about, yield a "can't make the goal easier in the akrasia horizon" error from the server when you hit the submit button.

I think #232 has the answer to replicating this so I'm tentatively closing this as a dup of that one!
