It’s about formatting. When you say UE4-20, the tagging reads it as UE4 v20 while you really meant UE4 v4.20. We’re on v4.27 not on v27. Wish the system was clever enough to know that.
The tagging system doesn’t allow for special characters due to the use of tags within URLs. Spaces get replaced with hyphens, periods get replaced removed, and the previous Engine version tags that moved across to the forums from AnswerHub were often just a series of numbers, i.e., 4262 for UE4 26.2 or 43 for UE4 3.0. The best solution was to format Engine version tags as UE4-VERSION to improve this.
The caveat is that expanding this to include hotfixes and updates to that version (4.27.2 as an example) would result in a tag that was UE4-27-2. While this may be preferable to some, the tag list would get bloated and result in less intuitive tagging for many.
As for the issue you are directly facing in tagging, we haven’t been able to reproduce this. Upon attempting to create a Question in that category, UE4-20 appears in the search and is taggable.
It seems that the requirements are clashing with each other. In categories relevant to a topic/feature/skillset of the Engine, they require a tag relating to the topic first; once this has been added, you can include the Engine version.
Well, it’s been WEEKS since this issue appeared. I can’t post anything because the tag is required, but there are no version tags anymore (there used to be a lot). Any temporary solution to that? Maybe just remove the requirement?
When posting a Question in a category, you need to select a tag relating to your topic and the category first; once you have chosen at least one tag, you will be able to choose an Engine version.
@SkyeEden If that is a requirement, you must add some help explain it because we only see a message asking for the version, without any other explanation, and we getting crazy trying to select a version tag that doesn’t appear anywhere.
I swear to god, not a single one of the listed tags are available when I search for them.
this is the category:
the sub-categories do not show up unless you already know what they are called so you can search for them.
nothing shows up when I search for “ue5” in tags.
selecting something else like “ue4” gives options like “ue4-editor” which is apparently not enough because it gives this error instead:
