Highway incorrectly affects costs for Saboteur

What steps will reproduce the problem?

AI played highway (reducing costs of all cards by 1) and then saboteur. 
Saboteur hit my gold.

My guess is that bridge or princess would have a similar problem.

What is the expected output?

I should be able to replace the gold with a card whose (normal) cost is 4; 
highway reduces the cost of the trashed gold but also reduces the cost of the 
cards on the table.

What do you see instead?

I was prompted to gain a card costing up to 3, and could not select cards 
normally costing 4.

What version of the product are you using? On what operating system?

2.02 on Ice Cream Sandwich on a Galaxy Nexus.

Please provide any additional information below.
