It doesn't for me, and the line you typed above makes it look like
you're subtracting lognormals from x.

Could you post a reproducible example?  For random number generators,
you can make them reproducible by using set.seed, e.g.

> set.seed(1)
> range(rlnorm(1000, meanlog =  0.6931472, sdlog = 1))
[1]  0.09877592 90.32586746
