Computers refuse to route a subnet range to gatway

Ok, Feels like I'm taking crazy pills here, I have a Mikrotik hap, the network is pretty simple, Lan is 192.168.1.0/24, wan is 172.x.x.x I can't remember, and it has a vpn using some ip in the 192.168.10.0 range connected to this other remote site where they use the 192.168.0.0/24 range, The router has no problem getting to the remote site, and all computers have a single IP with a dhcp address in the 192.168.1.0 range. but here is the thing:

Computers refuse to send ip packets directed to the 192.168.0.0 range to the gateway. If you make a trace from any computer to 8.8.8.8, everything is fine, do it to 192.168.3.x and you get 3 or 4 jumps before it get lost in the ISP, but if you trace to something in the 192.168.0.x range, i don't get even a single jump, and the MK doesn't get a single packet addressed to that range.

I disabled all rules in the MK, no firewall (exept the masquerade for NAT), no VPN, only one route (0.0.0.0/24 to the 172 gateway) or anything beyond the basic. only 2 networks Lan & Wan, and even added an explicit route in a machine (192.168.1.0/24 via 192.168.1.1) but nothing.

I'm not a great (or good (or even acceptable)) netadmin, and I'm sure I'm missing something obvious here, I would be grateful for any advice you can give me, I'm returning tomorrow to check if you can change the server address in some s**a* old soft so I can use some other range but 0.0, maybe do packet capture, i hate working with teamviewer.
