Strange crashes on some simulation runs

[bradduthie]

I have been getting some unusual crashes and error messages in some simulations. Specifically, I receive the following message sometimes:

Error in inds[i, 6] : subscript out of bounds

This happens when there is a population extinction; e.g.,

sim_bad <- gmse(land_ownership = TRUE, stakeholders = 24, observe_type = 2);

Rarely, a memory issue seems to be happening, but I can't get it to crash with any kind of consistency.
