I encountered an issue that I skimmed the internet and FAQs for without results, then asked SoulLink on the official Discord but they came to the conclusion as well that they have no idea how the bug couldn´t even come into existence, therefore reccommended a bug report:   I am currently working on a world titled "The-Realm". I priorly worked years agon on another world titled "The-Circle-of-Wildemount". Work on the latter world has ended a while ago.   I realized that some categories in the World View of "The-Realm" did not display the expanding Table of Contents (right under the category name), and couldn´t find a reason for it: Then I clicked the "Open Category Page" button and realized that a number of categories are linking to category pages in "The-Circle-of-Wildemount", and non-existing categories at that that have been deleted a long time ago - instead of the correct ones in "The-Realm".   There seems to be no option to "reset" the linking so I am stuck in that state.   The following things have been attempted to no avail to fix the bug:  

Category Hard Collapse/Reset

Category Refresh

Renaming the Category

Moving the Category to a different Category (and back)

Relogging

Changing the World (and back)

Unknown how the bug original came to happen. For the reproduction of the display of the incorrect category linking, see as follows:   1. Open World View of "The-Realm" tied to the account this bug report is made from. 2. Click on the "Codex" category. 3. Click on the "Organizations & Companies" category. 4. Click on the "Open Category Page" button of "Joint Ventures". It will correctly link into the same world "The-Realm". 5. Click on the "Open Category Page" button of "Cults & Sects", "Faculties", "Stateless Organizations", ... , "Syndicates". They will all link to the incorrect "The-Circle-of-Wildemount" world as seen in their URL, including a mismatch between the category name and the link-object name in the URL (i.e. "Stateless Organizations" and "The-Services").
