while looking at the last millenniumum portal, i went to the cobble thing and looked at the purple dye recipe. it closed my game and opened to the launcher with no crash.
Can you reproduce this? If so, please copy the client console into a pastebin.com url, after you have crashed again, so that we can see the exact cause of the issue
Does it also happen in SP? If not, could someone please provide the full /mt hand output, in SP, whilst holding the flower? If you cannot, then I'll load up Crundee in a moment. Hopefully, if the flower is used to craft purple dye, then I should be able to remove the flower from the crafting process
Already open issue with mod author. We can't patch the code server side, but can maybe disable the recipe. Right Clicking Purple Dye = Client Crash · Issue #52 · Tropicraft/Tropicraft · GitHub
The tropicraft flower => Purple Dye recipe is now gone, meaning that you will no longer crash. The other recipes for purple dyes still exist
