Encountering or not this error seems to be a bit flakey. I doubled the number of stock (resulting in shorter grazing durations) and no issues encountered for the first two years at least.
I'm examining the issue and it is likely to be in the calculations in Stock. Working on the fix now.
@her123 I see you closed your pull request #2700 and deleted your forageconsumption branch. Is this issue resolved now?
Yes. I haven't had any follow up requests so it should be closed. Thanks.

I am developing a simulation where the Stock component is grazing Plantain (eventually will be generic for any pasture/forage type plant) on a rotational basis. All is OK for the first year. At the start of the second year the grazing starts when there is a very high proportion of leaf on the plant and the error is that more leaf than exists is being attempted to remove.
I've attached the simulation and the error messae detail is below.
Thanks, Val
