Not sure what happened overnight: I have for a couple of days now been donating 399 meats to Mab under EHSP and gaining 1197 favour: just under my 1200 favour limit for an emblem, then spending it to speed up learning my gardening skills. No problems there. Only I just tried to do the same thing this morning and only received like 20something favour. Tried again, same story. Looks like I just blew a few thousand grand's worth of meat and EHSP on a fart.
Not sure what's going on there. A bug, or yet another nerf?
Edit: Just want to stipulate I made 100% certain (checked and double-checked) that I made no miscalculations. Started at 0 favour, sprinkled EHSP, donated 399 meat, checked, had 20something favour, spent it, sprinkled, donated the rest of my 300-odd meat again, same story – minuscule rewards.
