2d toolkit 1.8 on unity 4

[vambier]

I was using unity 3.4 to build our game but I now switched over to unity 4 and installed the 2dtoolkit 1.8 final + patch 2 via the asset store.
But every time an asset changes in my project the "rebuilding index" box hangs. In the console I get the following message :

NullReferenceException: Object reference not set to an instance of an object

Any ideas what could cause this?

Just had a look at this. Yes I can think of something which could cause it. Drop me an email and I'll get you a patch.

Looks like you may have a font which isn't set up somewhere in your project. Easier to skip over these than to manually find them in the project.

I've been out for a while, I mailed you about this, could you send me a patch for this? Thanks!

[unikronsoftware]

Just replied to your email. This issue is fixed in 1.90. I hope to release the final version in the next day or two.

[vambier]

Thanks for your mail, is 1.90 backwards compatible? If so I think I can wait a couple more days for that one:-)

[unikronsoftware]

Yup 1.90 works fine. That wasn't a Unity4 specific issue, it was a bug in 1.80
