New save system

In this patch we’re introducing a new save system, which should make managing your save files between game modes much easier. Here’s what to expect:

-You will now be presented with 5 save-game slots (each of which can be used for any game mode) - your existing saves will be mapped into these slots
-Selecting an empty slot will start a new game, allowing you to pick which game mode to play from the mode select menu
-There are now 2 sub-slots for each save-game (instead of 3) - one for auto saves, and one for manual saves
-Starting a brand new game with no existing saves will take you directly to mode select
-Note for experimental: while 1.37 saves are forwards compatible with 1.38, 1.38 save files are not backwards compatible with 1.37. For this reason, when you first run 1.38, an automatic backup of your 1.37 save file will be stored in your save folder, in case you wish to return to 1.37. See this thread for more info: http://steamcommunity.com/app/275850/discussions/0/2765630416830016499/

I don't see the stacking bug on the list of fixes. That's not good.

Neither are the looping NPC events fixed, and the new save system doesn't allow you to revert to an earlier savegame

*sigh*

Bug report time again.

-Fixed an issue where mining units would occasionally incorrectly produce Heridium

This still happens. Nitrogen from radon AHs too. Reloading a save fixes the AHs, not the AMU, as I recall.
It could have been the luck of the draw though.

Its here... well dl 5.6gb atm

Here is the finalized Patch Notes for 1.38. The stacking bug is fixed, according to this....

In regards to the Save System changes:
You basically have 2 slots per Savegame, one which will be overwritten each time the game saves automatically (i.e., when you exit your ship), one whenever you save manually (i.e. when you use a save item, like a beacon, a location marker or similar contraption - "manual" save is a bit misleading here). This can lead to enormous discrepancies between the two slots, especially if you have the habit of saving by entering and exiting your ship.

The patch also completely changes the save file structure - you might want to back up your save folder for safety reasons.
