Please test it for me.
OK, I tried and found the following:
1. both tiers (mib & xcom) of laser weapons are called just "laser" for me... I don't see "nuclear laser" anywhere (using en-GB)... same for ufopedia, same for production, same for inventoryEDIT: scratch that... for some reason my language reset to "ar"
the translation is now OKEDIT2: but the research topic is now called "Nuclear Laser xxx" even before I research advanced laser weapons... so it says for example research of "Nuclear Laser Pistol" finished, but I can only manufacture of course Laser Pistol...
2. as I was going through ufopedia, I found more items which are displayed sooner than they should be, this time Stormtrooper Armour... I guess you should check all items, which have been changed recently in the tech tree.... I think you've updated the research tree only and forgot about ufopedia entries (and maybe even production dependencies?).
I think it was all advanced armours, some advanced craft, advanced rocket launcher with various ammo, probably some more stuff...
