Some questions on vbulletin import script (groups, likes, attachments)

I see the following remaining formatting issues on my transferred forum. That is after the post clean-up scripts ran:

Lists tags aren’t fixed

[LIST]
[*]item 1
[*]item 2
[*]item 3
[/LIST]

I guess I should just remove the tags and the brackets round the * and add a space and it should be formatted right. Any ideas how? I can update the import script regex I guess? Looking for some regex genius help.

COLOR tags

[COLOR=#212121][FONT=Helvetica Neue]blah blah[/FONT][/COLOR]
[COLOR=#212121][FONT=Helvetica Neue]blah blah[/FONT][/COLOR]

This seems to come from posts that were made on the old forum by posting formatted text into them.

I guess best would be to just remove the tags? Again need a regex expert I guess?

Is this a bug because this is BBCode? Should this not be picked up? I didn’t for example need to use backtick to quote the above.
