uSkyBlock
This DevBukkit page is being updated again with current releases and links to the maintained uSkyBlock project. We had lost access to the DevBukkit project page for some time, but have now regained it and are bringing it back up to date.

Could you plz use the code format (cogswheels above the text) or use pastebin as this is to hard to read.
A full startup log will be more efficient to see for me.

We are working on some new challenges outlay in the GUI (as you probably have seen in v2.7.3).
I have suggested the noRepeatinXHours and have to wait for an answer of our dev.
Looking forward to the Czech translation to replace with the current one which is way outdated. I do presume the CS and CZ are the same language then?

OK, I think I know what's going wrong now. Also probably a miscommunication on both sides aswell.
You set resetInHours for 12 hours. This doesn't mean that the challenge can't be repeated for that time. It means that the challenge will be reset to it's default setting (+1) after 12 hours.
It's resetInHours, not repeatInHours
The cobblestone gen will set back to default 66 needed blocks after 12 hours no matter how many times they completed it.
All repeatable challenges can be repeated as many times a player wants (aslong they have the resources ofcourse)

I think I found the issue. Due to the "command(s)" given in some challenges your repeat issue is happening.
Try this version here and it should be fixed (do make a backup before updating).
Let me know if the issue still happens after this update.
PS. Is your cz.po file good for adding to the plugin so it can be chosen from ingame command? (for the update mentioned above you miss 51 lines now lol)

The issue's you have might be caused by the custome language file (CZ) you use. Try the challenges with the default language (/usb lang en) and see if it still happens.
If you can share the cz.po file (through pastebin) I can check if this is the cause.
