You mean their Drop Items are missing, right? Because they are actually missing. The Plants themselves do exist afaik.
No I meant the actual crops that are missing. Been crossbreeding for the past week and did not see any of them (did get withereed, steelleafranks and liferoot). Their seeds do not appear in nei either.
