Is it normal for shamrocks leaves to turn dark or wilt and get mushy? And although they have been in the place for years, all the sudden they are getting leggy. See pictures.
This can be due to a few things. Over time, without fertilization, they can start to show signs of deficiency. Feeding or repotting occasionally can help.
Alternatively, a lack of winter dormancy can cause issues over several years. They need that period of rest to remain healthy.

in the over 12 years I have had these shamrocks, they have never gone dormant, blooming all year round with full foliage. Is that part of the problem? and how do I know when they should be dormant?
I have had this plant years, in summer put outside, then it grows beautifully inside all year. This last month it's losing all its leaves. I want to save it as it is my favorite plant. Any advice you give me is appreciated. Thank you.
Try giving your plant a little fresh soil and an occasional feeding, plucking away the dead stems and leaves. Here's an article that should help:

In Southern Calif I am fighting both Kinds of weeds (oxalis and what looks like baby tears). The oxalis is in a flowerbed and the baby tears are starting at one corner of my lawn. I am willing to use a home made killer or gladly buy one. What would be recommended for both of these problems.

I bought and planted some clusters of already-growing dark purple shamrocks (oxalis triangularis) in mid-March The deer decided to sample them this week and pulled them out by their shoots. They apparently did not like them, though, as they were all lying there — presumably spit out. I’m pretty sure the bulb(s) are still in the ground. Will those bulbs produce new shoots this season, or will I have to wait until next spring to (hopefully) get foliage from them again? The picture shows the one cluster they didn’t touch and the three clusters that were pulled out. I replanted the shoots on the off-chance they might root themselves but they look pretty pitiful. Thank you!
If the corms are still there, they will send up new shoots.

The spots turn brown and the leaves are dying. New leaves grow and they then get the spots.
Here are the most common reasons for those leaf spots:

My shamrock plant (oxalis regnellii) is dying back, as articles predict. Should I pinch back the stems to the top of the soil, or leave them on when I set it in a dark corner of the basement for the summer?
This article explains. You can trim it back when the foliage fades for dormancy.
