I'm having an odd issue with agricraft since the update.
I did test with the same version of agricraft by itself (well, with Agricraft and Pam's) in otherwise vanilla minecraft, and this issue appears unique to this pack. I encounter the same problem in my old save, and in newly created games, but only within this modpack.
When harvesting crops, some crops seem to no longer give produce. At first I thought it was only Pam's crops having issues, but some Pam's crops work (ie rice seems to work fairly consistently) while most do not, and witchery crops aren't working, either.
When uprooting a garlic farm that was Pam's, it sometimes gives witchery garlic, as well, if it gives anything at all.
All vanilla crops seem to work (carrots and potatoes do not seem to work. It appears only wheat and netherwart work out of the vanilla crops), as does gysahl, and most grain crops. All other crops seem to only be giving produce when harvesting around 10% of the time. :/
I investigated further and found that the planted crops seem to disappear when bonemealed, but when the crops are broken, give the resulting produce? Irrigation seems to still grow crops as normal, though potatoes, carrots, and sugarcane do not seem to grow/respond to irrigation at all.
It's not showstopping I suppose, but agricraft and pam's are favorite mods of mine, and it does take some of the fun away of trying to make a ridiculous automated garden haha
