I just tried out Extended for the first time. Loaded an OXC save...
1. In Battlescape, what's the little number 2 in the lower-right corner of the psi-amp in my soldier's hand?
2. Why would the game tell me I'm missing mods, even though I carefully checked that I have exactly the same mods as in OXC? The same selection of standard mods, as well as this mod that transferred no problem. Should I worry about savegame compatibility from OXC -> OXCE?
3. is there a comprehensive list of differences between OXC and OXCE to be read anywhere? I don't just mean the ruleset referece, but features in general.
For example I see that the unequal LOS that leads to failure of mutual surprise when smoke is involved is solved. This is good, and important - but I do not see how I could know this if it hadn't been mentioned by some forum member in a conversation I was part of elsewhere.
1/ it's the indicator that it is a 2-handed weapon
2/ if you're missing mods, check if they have metadata.yml (this file is mandatory in OXCE)
if you're not missing any mods, upload the save here so that I can have a look
you don't need to worry about savegame compatibility OXC -> OXCE, it is 100% compatible
3/ there are thousands of fixes and new features in OXCE, the only truly "comprehensive" list of differences is a git log
more humanly-readable changelog is here:
https://openxcom.org/forum/index.php/topic,4187.0.htmlbut even this shortened changelog is a reading for days and days... there's 7 years of active development in OXCE
The LOS example (once confirmed) is likely a very early change (from before 2015), when I wasn't involved in OXCE yet, and thus not documented by me.
I'll check what the difference is and document it... but I don't think OXCE has equal LOS, as far as I know smoke does make it unequal also in OXCE, maybe in a slightly different way if you say it works differently than OXC.
