I understand that posts in archived topic cannot be liked or reacted. On that basis, how come this post can be liked (in a sense that you can press the heart, although it throws a ‘That reaction was created too long ago. It can no longer be modified or removed.’ error, which also is not correct).
Actually, this applies to other posts in that topic. Though it seems posts with likes/recations cannot be liked at all, but those with none can be, albeit with that error thrown.
This inconsistent behaviour makes me think this should be in Contribute > Bug, perhaps?
I think it’s because of the reactions plugin. I cannot do the same in safe mode. And I remember accidentally adding a reaction to an archived post back when Jammy was the community moderator. Since my reaction was quite inappropriate, he removed it for me, and I think something was added to prevent that in the future. But I am not sure, and finding that in our chat will take very long.
