4) Roman city E-W gates can't be entered. This is a bug we hope to fix, but for now, it is what it is. Don't report it. We know.
5) The "minor settlements" (PSFs) don't have walls. These are intended to be open fields where battles between armies take place. There's more than enough siege warfare as it is. Imagine that there's a town just beyond the range of visibility (most ancient battles happened outside some city or town, hence the historical name of the battle. Think of this as that).
6) Battles at "minor settlements" (PSFs) still go through the siege process. True. The game thinks these are forts, even if they aren't. And it assumes all forts have walls, even when they don't. If it takes an extra turn to get the battle going, think of it as getting force dispositions in place for battle the next day. Pretty common historically, actually.
7) The AI army sallied from the "minor settlements" (PSFs) but won't move toward my forces. True. It's technically a bug (the AI thinks there are walls, but can't find the gate so it just sits there), but the reality is, YOU initiated this open field battle. Thus you SHOULD BE the aggressor, and not relying on some gamey siege mechanism to get an advantage. And do NOT exploit this siege glitch to actually place AI units under siege in these PSFs. You are violating the whole reason for them being there in the first place. Or rather, go ahead and do it and screw up the quality of your game. Somebody who does this probably uses cheats anyway. A pox on them.
9) My fleets can't move past Gibraltar into the Atlantic Ocean. Other than down the small amount of North African coast. Impassable "ocean" terrain blocks movement to the north and west. In both directions and for all classes of ship. By design.
10) My faction doesn't have a Family Button. By design. For historical reasons, the M2TW "teutonic system" is used by several EB2 factions (mostly barbarians): Aedui, Arverni, Arevaci, Boii, Lugia, Lusotannan, Pritanoi, Sweboz, and Koinon Hellenon. If you must have families, there are 19 other factions to choose from. Given the reaction to lack of families in R2TW, this will probably prove controversial - that's fine, discuss it elsewhere (NOT in this thread). And don't report it as a "bug".
11) Cities have all this open space that my troops can't walk through. Those giant open areas? They aren't open areas. Those are the portions of the city reserved for temples, blacksmiths, govt buildings, etc. It was a minor miracle that we were able to bring the base-level DBM settlements into EB2. What we did not have was anybody who could bring in the various buildings that will grow into the afore mentioned structures. So not a bug, but a potential feature (some day).
14) The game CTDs after I click __ faction icons on the faction Selection Menu. This is an M2TW bug. There are reports claiming that it can be fixed, but we haven't been successful doing that with EB2. Just don't click a ton of different faction icons and you won't get this CTD.
16) The Game CTDs when I select one of the Tutorials. Unfortunately the Tutorials were never finished. Maybe some day. For now, we'll add warning text about this as part of the first Patch.
