Hi, sorry for spamming issues, but there is no other way to communicate with you about BlockHelper mod.
Now to the question.
I managed to get the IChatComponent backported to 1.4.7/1.5.2 and while it works just fine with displaying formatted text in GUI/Chat/Forge Overlays, I have a hard time getting it to work with block helper.

While it works just fine on client, on server the info provider isn't responsive (gives no info).

The IChatComponent module: component
The FormattedTranslator I use for messages.

Here is a simple example of how it looks in singleplayer.

Here is an example of my InfoProvider:

Oops. Turned out, some parts were client side only.
