Shardlight v2.1 - The Train Conductor Who Could.

Shardlight

A post-apocalyptic adventure game from the publisher that brought you Primordia, Gemini Rue and Technobabylon! A young woman stricken with a deadly plague searches for a cure in a hostile world.

-Fixed an issue regarding a certain train conductor and a hatch [you would reintroduce yourself to her] (To avoid breaking saves, this issue cannot be fixed in a savestate prior to this patch, the game will not stalemate from this issue, but it's just weird seeing the train conductor reappear. Regardless this is an issue that can now be considered solved, and won't repeat itself.)
