ETA disappears at 7th character

In order to reproduce this issue just run attached test.pwd with following command:
john --format=descrypt '-2=[xyz0123456789]' -1=?l?d --min-len=1 --mask=?2?1?u?1?1?1?1?1 --node=1467-4136/4136 ./test.pwd

Using default input encoding: UTF-8
Loaded 1 password hash (descrypt, traditional crypt(3) [DES 256/256 AVX2])
Will run 32 OpenMP threads
Node numbers 1467-4136 of 4136
Press 'q' or Ctrl-C to abort, almost any other key for status

I was able to narrow bug down to (what looks like) an integer overflow in mask.c in this line:
offset = my_candidates * (options.node_min - 1);
After commenting this line I could see eta but still not sure if it's calculated correctly, will do more tests.
test.pwd.zip

Start with mask.c and reproduce the behavior using the command and attached test.pwd. Inspect the offset calculation at the reported line and trace how it affects ETA and status output for the large node range. Done means ETA remains visible and is calculated correctly at the affected candidate length and node offset.
