I've had this issue with a few different modpacks with the Harvest Festival mod in them, and it seems like others are having this issue yet aren't being given a fix. When using the Farming Valley modpack on the twitch launcher, this issue came up immediately from my first interaction with the Harvest Goddess. However, when playing the Farming Harvest modpack on the twitch launcher, I was able to speak to Yulif and Jade and get going on earning some money; the text then stopped working after I finished the first few Jade quests and tried to give her more flowers. I can still exchange flowers for seeds, I just can't see what she's saying to me. Also, I was able to see the buildings options from Yulif before the issue arised, and now I can't. I will add screenshots below for reference:

After giving flowers, I still received seeds:

I've searched everywhere I can think for a solution to this issue, but it seems like there is none yet. Any suggestions with fixing this problem are greatly appreciated :)
