I'm adding new produced bonus - but something is still missing

[TheBirdMan]

It looks ......hmmmm..... special. But it's not ugly, not at all. Even here with a "close-look".

Spoiler Ironore in the field :

Close to be at the end of my wishes...... and happy to be so.

But there is one thing I do not understand with the Civilopedia:

Why can I add/change entries for some buildings without problems while a few building-pages (fx LargeStable) doesn't show all the details anymore. But if you remove the changes, the page appears completely normal again (screenshot not shown, but I have tried it)......

This looks like the page errors in the middle of being drawn, on the "and" bit in the requirements. Must be some error in XML that does that. It should also produce a meaningful error entry in Python error log, if you enable logging - you can share it here and it'll provide more insight. Or you can double-check the requirements in XML and see if you made any mistakes, such as referring a non-existent tag or the like.
