Instagram - tags not working?

So since last night I keep trying to post a picture, but the tags won't link. However, I just posted an unrelated picture with different tags, and it worked. I've used all the same tags in the past and they've worked fine :S? I've tried contacting Instagram but can't find a way to do so, and their help centre didn't help me at all. I've searched Google and people are saying it's when tags have more than 100k photos, but it's not that because I've used all the same tags before.

Anyone else experienced this problem or know how to fix it :(?

Fixed the problem, thread closed.
