Minecolonies version

Version: minecolonies-0.11.827-ALPHA-universal

Expected behavior

Upon starting a research, I expect to see research progress after at least 30 minutes.

Actual behaviour

The required items are consumed, after checking the University block after 30-60 minutes, the research has not progressed at all.

This image is research that has been going for at least 24 hours.

Steps to reproduce the problem

I do not have steps to reproduce the issue, however I do wonder if it's possible that as our world started before research was finalised in code, that the mod has got itself into a state that it did not rather like.

For example: We already had a hospital before we needed to research it.

If there is any data that would help you debug this issue, please let me know.
Will happily host the world somewhere for you to download for example :)

Hi I think I have same problem. How to fix it ?

Please don't necrobump old issues. 1.15.2 is not supported anymore.

Sorry i should have specified that, Yes i do.

The worker is running around, as i would expect going to bookshelves and the such.

I would like to point out, that it's possible that the university block is not always in a loaded chunk as it's built quite far from the main town due to building decisions by the players. I do not know if this matters much - but i thought i would say.

However, please note that we were building around the university for an hour yesterday, I say the above more in terms of the chunk will often be loaded and unloaded instead of being loaded along side the town hall block etc.

If the university or worker is unloaded they won't do anything

Fixed

The colony tick is crashing, that's why, we'll investigate it.
