PON 1.02 Patch candidate (public beta 1.01 serie N, updated Sept 16)
Hi everybody,
By popular demand, we are releasing the latest version of PON to everybody! Please note that this version is a "1.02 beta version" meaning that some bugs may remain, and some improvements are still on the radar.
It is safe to say though, that this Public Beta version will provide you an even better gaming experience than the current 1.01 version you are playing with.
Once all issues are fixed, and after the QA department has validated it, this beta patch (internally called 101 N) will be made official and will become version 1.02 (very soon!).
STEAM users can patch PON using this setup. You'll have either to make a separate copy of PON and apply the patch there, or be sure to not have Steam 'update' your game, as this would revert it to the last official version, which is 1.01
LINK DELETED ON PURPOSE
FIXES AND NOVELTIES 1.01n
Engine & AI
Structure cost now properly shown in tooltip (including the penalty for many structure, every fifth structure).
Adjacent territories when liberating a nation were not freed reliably (even if qualified as to be freed). Warscore costs in the interface was erroneously too low (fixed).
Foreign investments in structures will be costlier and more dangerous (more chance to get seized).
In some cases, elements could receive replacements without any spending from mother nation.
Windowed mode should now behave as expected, resolution-wise.
The game will now pause correctly (if pause on battle is chosen) during turns, without generating display glitch.
Declaring a protectorate in a region with a significant colonial presence from another country can generates automatically a crisis now (no need to have a stake/contest stake decisions issued).
AI has added interests in selling or buying non critical merchandises (like tropical fruits, etc.)
Tradepost now generate their goods later in the turn, so that stockpile situation is clearer for the player.
AI will favor even more strongly the presence of railroads when seeking a construction site.
Crash when doing a distant unload fixed.
4 colonial structures, when placed, lower others nations CP by 5 each: Mission, School, Dispensary, Outpost. This can be seen as a tool to sap away the influence of others colonial powers.
New window, listing structures (F11 key).
