It may have taken more time on my save is all I mean. You said you fished three times for 8+ hours, which does equal the 24 that I said it would take at minimum, but it may have taken two days. I'm not really sure.
Well, now I'm really uncertain. I'd read your earlier post that said "more than eight hours," so I fished for 10 or so hours those two occasions then gave up and went home. I'd missed your mention of "at least a day" (how did I overlook that?). After I reset, I didn't wait long until the chamomile plants reappeared (unharvestable).
Because I ecstatically saved as soon as I got the toxic cham cutting, I tried going back to a pre-reset save file from two sim days ago. After spending 24 hours in the lodging area, no chamomile plants appeared.
I think what this means is that your save file and my save file suffered from different problems requiring different solutions. I wonder if this is caused by the different plants (chamomile/fireleaf) and areas (lodging/national park) involved.
For me, the good news is that we have options. The next time, I will again try waiting first. If that doesn't work, I'll try a factory reset.
Thanks for all your feedback. You're a really amazing player, ClayMask.
