Has Good Loaf Gone Bad.???

We've been baking bread in our Kenwood BM450 for awhile now & each loaf has been perfect but last nights one not so sure so here goes:

For 1 kg loaf

Water 380mml

Wholemeal bread flower 600g

Skimmed milk 4 tsp

Salt 2 tsp

Suger 1 tbsp

butter 25g

easy blend yeast 1 tsp

Then set b/maker to (3) = 4.35 & once completed" loaf was not quite as high as previous loafs so where did i go wrong.?

Loaf once cooled had a tacky feel when cut with knife but tast was as good as previous loafs but with a very slightly tacky edable tast, next day checks was as per night before but pleased there was no shrinkage of the loaf & tast was as good as previous night so do I carry on as per my ingrediants or what would you suggest...???
