Default values and assetbundles

[gislesolvberg]

Hello
After updating to 2.7.0f1 I have been experiencing some trouble with setting values directly on nodes included in asset bundles. Everything seems to work fine in the editor but when I build my bundles and run the game some of these values are reset to their default value. I have only noticed this happening with bools, even though I set the node value directly many other places. If I connect a bool variable to the node the issue seems to disappear.

The nodes are part of a bound canvas within a scene, which is then included in a bundle.

I’m hoping this is a bug, as it was working fine in the previous version, and I really like being able to set the value directly on the node.

When I build the asset bundles, I get this error from unity, also new in this version:
This particular error seems to be concerning the Color type, but I get 100s of the same error concerning other data types.

Also getting this error when building. Fixed it by null checking the texture object being accessed from the dictionary, which should not be null in the first place.

Thank you, I tried the fix and so far it seems that it solved all my problems. Cheers!
