As from the above post, it may be apparent that you are making multiple threads, if so, this will not help fix the bug.
I would advise you to include video / screenshot evidence where applicable. You will also need to describe what was happening, where it was happening (what gamemode, version etc), the time of the event and also a ./whereami if possible.
This way the developers will know exactly what happened and will have a better chance of fixing it.
The reason you are kicked may not be caused by Cubecraft, you may have a faulty/slow connection.
Please make a report of the bug and post it here:
