Vlan Host cannot ping Layer 3 core switch

[banana-spectre]

Hello, I am a beginner in packet tracer. In here, I'm using access, distrib (has trunking), core switches shown in my topology below.

Any PC from a vlan can ping the distribution switches and PC from other vlans, while the distribution switches can ping the core switches. However, the PCs from any vlan cannot ping the core. Tracert shows the first and last succesful hop is at 10.0.2.2 (or vlan ip) in the distribution. Show int trunk reveals that I have indeed allowed the vlans. 

Distribution switch config snippets:

interface GigabitEthernet0/1
 no switchport
 ip address 10.0.2.165 255.255.255.248
 duplex auto
 speed auto

interface Vlan10
mac-address 00d0.ba9b.9001
ip address 10.0.2.2 255.255.255.224
standby 10 ip 10.0.2.1
standby 10 priority 110
standby 10 preempt

router eigrp 100
 network 10.0.2.0 0.0.0.255
 network 10.0.3.0 0.0.0.255
 no auto-summary

Core switch config:

interface FastEthernet0/1
 no switchport
 ip address 10.0.2.162 255.255.255.248
 duplex auto
 speed auto

router eigrp 1
 redistribute static 
 network 10.0.2.160 0.0.0.7
 network 10.0.2.168 0.0.0.7
 network 10.0.2.192 0.0.0.7
 network 10.0.2.176 0.0.0.7
 network 10.0.2.216 0.0.0.7
 no auto-summary

access-list 10 permit 10.0.2.0 0.0.0.255
access-list 10 permit 10.0.3.0 0.0.0.255

I have no more idea at this point and I have been trying to solve it for three days now. I am not sure if I am indeed overlooking something. Thank you.

Edit 1 - added zip file. Please disregard the other sites, it suck.

Hi

 Try to share your pkt file so that we can help you.  You  may need to zip the file in order to attach.

Added the file. Thank you.

Nvm. I reconfigured everything back to square one and somehow it worked now.

Hello,

Packet Tracer is quite quirky, sometimes you have to reload devices, or wait for quite a long time before a command actually takes effect. Either way, you got it working...
