Border blobs issue

[crdvis16]

I'm in a game as Russia and went all in with the border blobs strategy (stacking bonuses from border expansion with policies/wonders/UB that increase border expansion speed). However, I seem to have hit an unexpected issue- my cities don't seem to expand beyond a 5-tile radius even though there is unclaimed space (mostly ocean) available at 6 and 7 tiles away. I'm in the modern age now and basically not getting any ticks of border expansion bonus anymore. For some reason I thought the limit on border expansion was something higher than 5 tiles- am I wrong or is this some sort of bug?

Limit on border expansion has always been 5 tiles.

Ah, thanks. I vaguely remember reading someone post that the limit was much higher, like 7+ tiles at one point. That certainly creates a problem for the border blobs strategy later in the game when you stop getting ticks I suppose. Also makes the Ostrog significantly less useful as many of your cities will probably hit the limit before you're able to build it.

More cities, more blobs.
EDIT. Raze and settle again if you need more.
