I make it simple with screen shots: Create a simple project with LCSC# C33196 (PCA9306DCUR) ( Photo 1).After hit Convert to PCB (Photo 2).Then use Auto Router with local server (photo 3).At the end Connection closed with unrooted wires(photo4). I found that : I have an old project with this component that working fine.I try to clone (copy paste) in sketch mode and the convert to PCB.Again the autoroute is not working.Of course if i deleted the autoruter works fine. After a lot of searching i found that the order of properties in Custom Attributes menu are diffrent between old component and clIf i delete and renenter the properties of clone component then finaly everything is working. So i believe the probem is when converting to PCB the component attributes are delivierd in wrong order. The same problem exists also with PCA9306DC1 , LCSC# C129510. 

@george.chalkidis, Thank you for the detailed information that you have provided in support of this Bug Report however you have yet to provide a url to a public project that demonstrates this issue. As you will have read in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> as a courtesy to the people whose time you are asking to give up to help you, you should make every effort to save their time in having to recreate a schematic and PCB _that you have already created_ in order to post the detailed information to demonstrate this issue. * Please post the url to this demonstartion project.

I have found that the problem is more general\. When i use LCSC footprints like SOT\-23\-6\_L2\.9\-W1\.6\-P0\.95\-LS2\.8\-BR \, VSSOP\-8\_L2\.4\-W2\.1\-P0\.50\-LS3\.2\-BR the problem exist\. When is use system footprints instead of LCSC the problem disappear\. The above footprints from LCSC was working before 1 month ago but suddenly stop working \(autorouter stuck\)\.I try to downgrade easy eda and also use other laptop but unfortunately with effect\.

Please pay attention to the Forum ettiquette of saving the time of the people who are trying to help you by posting the url to a public project that demonstrates this issue. You must have created one already so please make it public and then post the url to it back here.
