FILE_WRITE does not work properly since v1.2.0

[Nightenom]

Command: File file = SD.open(target, FILE_WRITE);
How it looked like (version 1.1.1):

Reading file "/logs/log3.txt":
[26.11.17][12:59:03][4893] S: GSM: ready without restart
[26.11.17][12:59:08][9526] I: GSM: IP: "100.90.60.208"
[26.11.17][12:59:17][18051] S: RTC: synced
[26.11.17][12:59:17][18077] Boot successful

Done!

How it looks like (version 1.2.0),
it always write to first line:

Reading file "/logs/log0.txt":
[01.01.04][00:47:39][60621] Boot successful
86.142.157"

Done!
Reading file "/logs/log1.txt":
[01.01.04][00:52:55][32144] I: GSM: IP: "100.90.60.208"

Done!
Reading file "/logs/log2.txt":
[26.11.17][12:40:57][18082] Boot successful
0.60.208"

Done!
