When you play a Forge, it prompts you 2 times to do something: At first it asks you to trash cards, then to select a card to gain.
The prompt in the log area is OK, but the prompt in the central information area (where the active players' Actions, Buys and money are displayed) looks like it is simply the log prompt that has been cut off at some (inappropiate) point:
1st prompt
Log prompt: Trash any number of cards from your hand.
information area prompt: Trash any number
2nd prompt
Log prompt: Gain a card costing exactly 2.
information area prompt: Gain a card costing
(See attached screenshot).
The German and Russian version seem to be fine, there the text in the information area is a (meaningfully) shortened version of the prompt.
