Hello im new here. just bought the game Two point Museum and i saw that if i link this county to my game i get e free golden Helicopter but i dont think i recieved it.

i linked steam and twitch now but so far nothing

Its an alternate skin for your normal helicopter rather then a sperate item in its own right. 

So where do you set this alt skin?

Select the helipad by clicking on it, then on the bottom of the Information Panel there's a paintbrush icon ("Customize Item"). It is only available when the helicopter is at the landing pad, i.e., can't make changes during an expedition.

To revieve the Golden Heli skin you need to sync ur Twopointcounty Account with the game 

but for some reason it keeps saying my internet connection is not valid so i cannot connect 

anyone have a solution ?

We should be given the skins and not have to connect to two point county to have them when we play.  Then if the Internet drops our connection the golden gifts won't disappear.

Otherwise when the ISP is having any problems so people with Internet service get disconnected because the ISP service crashes at their end on the ISP's Server, having the golden objects in our computer cache so they will always remain after we have them in a save on our computer is better.

Then If we lose the Two Points County connection because of the Internet Service Providers weak signal, we won't lose the golden helicopter, bath time, golden thumbs up duck, or any of the gifts having the Explorer DLC promised us.
