[Can't complete "Splash down test" missions.]

Thanks to all for your help. I ended up  creating the smallest four wheeler and driving the pieces that needs testing right in the water at the end of the runway. Super cost effective.

to test a wheel, you need to open the wheel's "context menu". There will be a button at the bottom that says "Run Test".

Yes! That's what i was missing. Thank you very much.

[Can't complete "Splash down test" missions.]

Hello to the KSPC,

I've joined the Kerbal space race recently, and i've come across a type of missions i can't seem to be able to complete.

i.e:

Test Rockomax Brand Decoupler splashed down at Kerbin

Test Rovemax Model S2 splashed down at Kerbin

When i complete those missions, the 2nd and 3rd  ("kerbin"  and the "splashed down") lines get the green check mark, but the first line the one that says "Test..." doesn't.

Could this be a bug? Has anyone had the same issue? Or am i just doing something wrong? Guidance needed over here!
